Now, on to your list.
Looks like a good list so far, definitely work in progress. I would drop the dread and add a death roller to the BWs and beef up the tank bustas. Take the nob with a boss pole, but let him keep his rockit launcha. 15 shots, will kill most everything in this game.
In the last two games my tank busta boys were my anti-aircraft, so far they have shot down three DE bombers and two of the necron bombers. Yes you are firing snap shot, but with 15 shots you are going to roll sixes, my average was four sixes, sometimes more but never less than four. And this usually led to planes blowing up in mid air; Good Stuff!
Something you may want to consider for the future is to split your 30 boy squad into 12 boys each, and putting them into trucks. They can still snap fire moving the full 13, with a minimal loss to their BS. Makes a whole new meaning to drive by shooting
When you get a plane (and you will) I recommend the burna bomba, I have had some great success with mine, and he has actually survived over half his battles. While my dakka jet gets shot down every game. I find my dakka jet to be like an overpriced green baron. You know, show up, kill something, die. I also recommend rockit buggies, a squadron of three rockit buggies costs the same as a dakka jet with extra shoota, but twin link rockits are starting to become valuable again, so I am dropping my dakka jet for rockit buggies, and will use the jet only in larger games where I can take two force orgs.
Just in case you haven't noticed I am a speed freak, a dedicated member of the Kult of Speed, and lover of red paint. I suggest that since you have already started to succumb to the green side, you might as well go in with both feet and become a speed freak as well. The joys of going fast, and red paint are just too numerous to mention here.
