Plenty of good advise there from Col.
You can't go far wrong if you buy similar kit, or at least gear with a similar spec. I have the Turnigy SK3 motors from hobbyking uk, these little fellas :

They are great on the 330 - but on the 450 id want to go a tad bigger, maybe this one from again the UK store.

The Uk store has lots of motors that can be used - they are not listed under the multi rotor section though as they had full length shafts as opposed to short shafts. Not a problem, just means the shaft protrudes through the frame arm.
KK2 is the one to go for - it's so easy to change stuff. If they make a KK3 with GPS then I reckon DJI will not sell another Naza !
I'm using the Turnigy 9X radio and receivers - so far with no problems. Just using it as it comes as I don't fly that far away from myself. No FPV for me yet.
If I was (and a I am considering) going for FPV and ariel photography, then I would go for the Naza light as the return to home and gps is a lifesaver. With the KK2 you are on your own, if it goes wrong, it's bad. The ArduPilot 2.5 looks ace too, but not as plug and play as the Naza.
I bought the 330 to learn to fly. Ive flown it into a tree, mustered up enough courage to flip it and skimmed the ground and rolled it along the ground a few times - so far very few breakages. I did one arm after panicking as I hit a big tree and the quad fell quite a way to the ground !
As Col said - whatever you go for (frame wise) buy 2 and get a few extra props. I'm running 8x5 on the 330 and 10x5 (I think) on the 450.
A prop balancer is good to have as the cheap props are badly balanced.
Also, buy a few lipo's. I use the Nano Tech 2650's at around £10 each - bargain. Also you do not really need higher C ratings. I've tried 20C and 70C cells and can't tell the difference.
Also - esc's - it seems you don't need silly highly rated ones for a Quad. My 450 flew lovely with 18amp esc's - although I have put the new Afro ones on it now.
Be careful - this stuff is addictive
