You could start with getting the latest beta and plugin pack here, and then read the guide. If you have any problems come back. Its kinda hard to just say what plugins are best. The best plugins depends on the game and may vary from pc to pc.

Actually, just make sure you use GSdx and SPU2-X. Those 2 plugins are really recommended,
and the alternatives should only be used for (rare) compatibility problems.
The other component's plugins don't make much of a difference. Use what fits you best.
