Also a side question:
If one were to buy a couple of FW Thunderhawk transporters does it matter which of the three?

I'd suggest going for one of the transporters for one reason alone. I recently got the Gunship and, although it's a nice model, those small forward wings and heavy-bolter sponsons are very fragile. The landing gear is too but all 3 have that but the transporters look to be sturdier. Mine is still in one piece but I know it's only a matter of time before I lose a bit. As Jimmyzimms says, just tell your opponent which one it is at the start and it won't be a problem.
On your other question it's often best to take a mixture of units. Scouts are very useful (most people take at least one unit). AA can be handy but it depends on your opponent. Terminators teleporting in can make a big difference.
Although I'm relatively new at this I'd suggest going with what you have now. Mix it up as much as you can (not all tactical units, for example) and see how you get on. Chat with your opponent(s) and start tweeking as you learn how you want to fight and how each unit is most effective. There's no one answer (although few marine players seem to ignore the Thunderhawk loaded with Assault, and possibly Devastator, Marines combo, thats nasty).
