Change one of the HQ choices to a Chapter Master, and convert the other to a Liberian or Chaplin. Two captains in the same army is rather unfluffy.
Take off five of those Termies, turn one of the dreads to Venerable, and convert a Heavy Flamer onto them both. 400 points of termies is too much, considering what you're going after, the points would be better served into your dreads, so you can get some anti-tank into the list.
As the above guy said, try to get some Sniper Scouts (And, perhaps some standard scouts, so you can get that heavy bolter and those lovely hellfire shells.) to help with objectives. As for Teleport homers, if you get scouts and you're planning to use Tele-homers, be sure to give one of the scout squads a tele-homer, Five Termies busting out of cover with a set of scouts behind them is always a nice sight on turn 2.
Drop-podding one of your Dreads wouldn't be a bad idea either, seeing as you're using a pair of AoBR dreads, and they both come with Multi-Meltas. Nothing like a S8+2d6 to the rear armor of a tank. or a Monstrous creature.
