It really varies with the chip. I've given my chip 1.625V (before VDroop) and it's been fine. There are others who can't even hit 1.5V.
On my AMD AM2 Athlon, I try to keep full load temperatures under 55c. If you take it step by step you should be fine. AMD says their processors is supposed to withstand 70C, but I would keep that max at 55-60C.
Also, because you don't have an unlocked multi, you'll have to rely on the CPU frequency. This will put stress on your RAM and a little bit on your NB. So if you want the best OC, make sure you have some good RAM.
