Okay, here's what I'd drop from your list and why.
Commander - 194 (Calm down Wyddr! )
Missile Pod x2 Vectored Retro Thrusters Target Lock Shield Drone x2 Puretide Engram Neurochip Iridium Armour Onager Guantlet
Okay, you aren't going to like this, and we've discussed it before, but just to reiterate:
Vectored Retro Thrusters: As Unseenly Invincible says, these only come in handy when you've screwed up and you frequently don't live long enough for it to matter, anyway. Ditch them.
Shield Drones: I do like Shield Drones, but no unit really needs more than two. Since this guy is going to live with the crisis suits (and only the crisis suits--he does not belong on his own and you should never have him do it except as an act of pure desperation), you don't need the drones here. You could keep them here, I guess, but in any event I'm cutting 4 shield drones from your list.
Iridium Armor: You really and truly don't need this half as much as you think you do, especially since your commander should never ever be going it alone.
Onager Gauntlet: Waste of points. Your commander does not exist to punch things. If he winds up punching things, I am forced to ask why a jetpack wielding dude with long-range missile pods is getting close to anything at all.
Commander Savings: 59 points
Riptide - 275
Early Warning Override Stimulat Injector TL Fusion Blaster Ion Accelerator Shielded Missile Drone x2
Okay, first off your Riptide is hard enough to kill all by his lonesome--he needs no defensive upgrades. Secondly, you *want* people to shoot at your Riptide, because he can take it and he loses nothing by losing wounds. All of these defensive upgrades simply mean nobody will bother shooting at him (unless they're dummies), which is the exact opposite of what you want. On a side note (not a points thing), Smart Missiles I feel are better than Fusion. This guy has no business being within melta range of anything.
So:
Stimulant Injectors: Only worth the points if you do something weird, like take the Heavy Burst Cannon and are Nova Charging its gun every turn (that's an average of two FNP saves a turn and two nova malfunctions). As it stands, it is WAY too expensive for its benefit.
Shielded Missile Drones: See above about 'wanting people to shoot at it'. When you're rocking the Ion Accelerator, you're firing the big pie plate every turn (or you should be). The Drones, with their crap BS, do not add much to the huge template, seeing as you're only averaging 1 hit per turn of firing and this means you just aren't doing damage to tanks or terminators, which is the Accelerator's targets of choice. I could *maybe* see taking a target lock on the Riptide to keep them shooting at other stuff, but they still suck at any job but soaking hits and the Riptide doesn't need the help.
Riptide Savings: 85 points
Crisis Team x3 - 219
Missile Pod x4 Shield Drone x4 Shas'vre with Spectrum+Node
Ditch two shield drones, since two is plenty.
Spectrum + Node gives you two abilities you can get without having to pay the premium of a Shas'vre. Here's what to do:
Crisis Suits x3 w/Twin Linked Missile Pods, 2 Shield Drones
Yes, you have two fewer shots. Yes, you don't get to ignore cover for free. You do, however, have access to markerlights for the cover and you get the twinlinking even if a certain guy dies. Also, since the Commander is going to stay with them all the time (all the time.), they get four more shots plus get the Tank Hunting from the Puretide. That's plenty, especially since I just saved you 69 points.
Crisis Suit Savings: 69 points
(savings to date: 213 points!)
FireWarriors - 249
Puls Carbines Shas'ui Gun Drone EMP Grenades
DevilFish Disruption Pod Flechette Discharger
A while ago I tried to think of units that would assault my tank and kill it but would be stopped from killing it by a Flechette Discharger. I came up with one unit: 5 Wyches with Haywire Grenades. After that, I ditched them. Keep the EMPs if you want--I'm curious to see how they work and I think they might have potential. If somebody has flechette dischargers, don't sweat it--you'll probably only lose 2 guys and still blow up the tank. Also ditch that Gun Drone, because the Devilfish comes with two for free and they are much, much better.
Firewarrior Savings: 24 points
Kroot x10 - 90
Sniper Rounds Kroot Hound Shaper
Shapers are among the worst unit upgrades in the entire game and always have been. For a couple more points you could have three whole additional Kroot which would add a lot more to the unit. Ditch him.
The Kroot Hound is there in those (rare) instances where you absolutely need your disposable crew of bird men to pop out on a flank and rapid fire people with their crappy weapons, miss, and then stand there with a stupid look on their face before dying in a shower of alien goo. Seriously, if you have to outflank, the Kroot are good enough at it by themselves--the reroll is rarely necessary and the hound serves virtually no other purpose that matters. Kroot upgrades are like putting racing stripes on a bulldozer.
Kroot Savings: 20 points
Savings to date: 257 points!
Hammerhead - 191
Railgun Submunition Rounds TL Smart Missle System Seeker Missilex2 Long Strike
I'm not 100% sold on Longstrike, but if you want to try him out, be my guest. The seeker missiles, though, aren't going to come in handy too often. If you have points lying around, that's one thing, but they are the kind of purchase you make to fill out those last few points because nothing else is needed.
Hammerhead Savings: 16 points.
Total List Savings: 273 Points This is a crapload of points, as you can no doubt see. This is a whole additional carbine in fish unit plus change. This is 5 Fusion Piranha + change. This is a whole additional Riptide (if you had the slots--shame that). This is a Sunshark + a unit of Pathfinders. This is a second Hammerhead + another unit.
All of these cuts make a few of your units less resilient, but not so much that you'll notice too much. You won't notice because you'll be flooding the board with more threats and making the threats you have less threatening. It will be harder for the enemy to select targets and you'll be hitting him with more stuff that works all the time as opposed to 'on a rainy day'. About the only shooting you lose is a handful of Strength 7 shots, and if you feel that strongly about it, you can easily buy yourself another 10 Kroot + 3 Krootox and still have enough left over for another Skyray.
