They come out June 20th or around that time.
This way your computer will have the latest and will be future proof for a long while.
Stick with the 6950 for a while as you can upgrade graphic cards easy.
When you do buy a Bulldozer cpu, you'll need an AM3+ motherboard, not an AM3 socket.
You'll have the option of doing 4GB DRR3 or 8 gig DDR3. If you do 4GB (2x2GB you'll be able to still put in 2 more RAM sticks for 4 more gigs in the future, just make sure your motherboard has 4 slots for DDR3. I also recommend 1600 MHz DRR3. Lower the Cas latency the better. You'll want 7 or 8 cas. 7 is much more expensive than 8 though.
The Power supply I showed you will be good for a while, or go ahead and get a Corsair 750TX for future proofing your power supply.
The case is a mid range gaming case, it's cool, simple, and cheap and will allow plenty of room for cards and is great for modding imo
