First list:
Not bad, though you've got a lot of Flayed Ones.. you either own the models or really like them is my guess
. The list itself looks fine, though at 1k it's hard to deal with combinations that people come up with, so you could face some hard times. Try to play larger battles if you can, since that's when Necrons start to perform better. Other than that a pretty nice balanced list.
Second List:
Your squad sizes are too small, in my opinion. Both the Immortals and Destroyers need larger squads, you don't want them to get wiped out in a single round of shooting.. I'd recommend dropping one of the Destroyer squads, and using the points to add to other two squads like 4 Destroyers and 8 Immortals instead. You also might want to consider dropping the Flayed Ones numbers to 8, and using the points to boost your Scarabs numbers and/or Destroyers and Immortals again. Or maybe a Warrior from each squad
really anything to boost those squad sizes. Since they're your heavy hitters you want them to stick around for as long as possible and deal as much damage as they can.
If you're having problems with Terminators the only real solution I can suggest is a Lord with Warscythe. Make sure to put a LOT of firepower into them first then clean up with the Lord. He's Tough enough to avoid instant kill, and with your Phase/Ord will have saves and WBB. Combine his charge with the Tomb Spyders and you should do allright.
