Sumdumguy,
Sorry you're having problems. It might be worth opening Activity Monitor in your Utilities folder and see what processes are running. I just cured a friend's slow iMac by finding that a PowerPC-based process was running (!).
If you have had any Safari plugins, some of them are only 32bit. They shouldn't load in, but some might cause issues. The most popular is probably Safari Ad Block which will only run in 32bit in Snow Leopard. This means you have to make Safari open as a 32bit application:
Applications>Safari
Click on Safari once to highlight it, then select Command-I to get the Info box up. Once there, click the "Open in 32-bit mode" box.
