Looks like an ok group of stuff for Chaos. The thing about Chaos Space Marines is they are getting revamped sometime in the next 6 months as they are being released with the new edition of Warhammer 40k. For the time, though, you may find yourself a little frustrated with the army as the current codex is definitely showing its age (says the guy building onto his Eldar army). I've never seen anyone use the Raptor squads (I think that's what the jump pack group is called), but with the new FAQ up at the GW site your Dreadnought should do alright (put it in front of your units so it can't frenzy fire on them if it comes up).
The popular way to run Termies in Chaos right now is as a 3 man melta squad dropping close to the enemy to destroy a tank.
