you should be ok with that, except I would suggest the AS Rock 880 for $59.99 and skip the weak 210. The 880 has enough video card for anything short of 3D Gaming, and the 210 won't do gaming. I'd also get 4 GB of RAM.
* If you install AMD AM3 CPU on this motherboard, the system bus speed will downgrade from HT3.0 (5200MT/s) to HT1.0 (2000 MT/s) spec; however, the frequency of AM3 CPU will not be impacted. Please refer "CPU Support List" for more information.
If you are not gaming, stick with the IGP on the 880 motherboard. Its great for everything up to and including 1080p Blu-Ray movies, but it won't do 3D gaming.
The 210 will do about the same, meaning no point getting it. If you plan to do 3D Gaming, you want a GTS 450 or HD 5770, minimum, which run $110-$130.
80+ PSUs mean they are certified 80% or better in power efficency at load. 80+ means 82% or better, 80+ Bronze is 85% or better, Silver is 88% of better, and Gold is 90% or better.
Sea Sonic has a 300W 80+ Bronze for 39.99, 350W for 49.99, and 520W for 59.99. the 300w is fine if you don't need a graphics card, or use a lower power one that really can't do games anyway. The 520W model is the one to use with a lower powered video card that needs only 1 PCIe plug (the GTS 450, HD 5770, or HD6850 in modern cards).
