This is only my second build (first was four years ago) so I was hoping that one of you folks might be kind enough to stop me from making any huge mistakes.
This system will be used for intense 2d photo graphics processing (with Lightroom, which expects multiple cores these days), general home use, and occasional gaming. This last is why I went for the 4850 graphics card and the 750W power supply, though I'm open to being told I'm an idiot in this regard. I tried to set things up so that I can add a second 4850 to upgrade to crossfire if I decide I want it down the road. I plan to experiment with overclocking a moderate amount but don't feel the need to push the limits, which is why I went with the DDR2-800. The NAS enclosure and 5600 RPM drive are for offsite backup at a friend's house.
I already have 1 x 750gb WD Caviar (to be added to the additional 2 and linked RAID 5 for ~1.5TB) and an NEC 2690WUXi monitor as well as keyboard, mouse, speakers, etc...
Aside from a general look-over, I'm specifically interested in anywhere I might be able to save money or improve quality without losing too much performance or reliability and whether or not I'll need an aftermarket CPU sink for moderate OCing.

Well your raid 5 setup looks okay but I would only do a raid setup with 2/3 brand new hdd's. You could always use 2 and stripe them, having a 3rd, external drive. I would go this way because what if you get a power surge and then you would lose all three disks.
Also, I would recommend 4 gigs, especially since you have 64bit, you'll be able to see it. The 750W PS should be enough...you do say 650 though (I think it's just a typo).
If you will be using multi-core enabled software, or heavy multitasking, then you should consider the i7 920. The cpu will actually cost less than the Q9550. The other parts will be more, though. A X58 msi motherboard will be $220, and 4gb of 1.5v DDR3 will be about $125
3 typos, actually. I had intended to get 8GB RAM (4x the 2GB stick, though the kit geofelt mentioned is even better) since it's so cheap. I was also planning on 2 of the 750GB drives and the PSU is supposed to be 750W. I've corrected the original post. Sorry!
I did consider the i7 but figured I'd go with the more tested technology (both CPU and MoBo) for now since I'd need to upgrade both and the DDR3 prices are so high. Maybe I should take another look, though. Thanks.
I'm a lazy backup guy. The plan is for RAID5 onsite and a NAS backed up initially by connecting to the drive directly and then leaving it at a friend's house for incremental backups via ftps.
