Video card OC and settings

[gospel]

With rivatuner and the nview desktop manager I have overclocked my video card. I have gotten good results, but really don't know what I'm doing. I have a Geforce FX 5200 128mb card. I know it's not the latest and the greatest, but it does what I want it to do for now (plus it only cost me $40). I will just list my questions and would appreciate a little explanation of what the terms mean and recommended settings.

1. How far can I overclock?
2. What should screen refresh rate be set at?
3. What is antialiasing? Is the best setting application controlled or something else?
4. What is anisotropic filtering? Is the best setting application controlled or something else?

Thanks in advance for any help
