In general, insufficient relief will cause more buzzing on the lower frets, and too much relief will cause buzzing on the higher frets.
With the first and 24th frets pressed down, you should have about enough room to slide a credit card in a the 7th fret. If you have a feeler gauge, try for about 0.015", give or take 0.005". Just loosen the truss rod a bit at a time until you have it set.
Once you have this set, you may still experience fret buzz. At this point, you simply need to raise the saddles a little at a time until it disappears.
With the relief set correctly, you should be able to get the action down to about 1/8" of an inch clearance at the 24th fret, depending on how hard you play.
If you find that you have to raise the action unreasonably high, you may have some worn nut slots, or a high fret somewhere. At which point, you'll probably need a pro. As in, not someone who works at the store you took it to before. And not Guitar Center. Find a local mom and pop that the local musicians like. Try to talk to bass players in your area to see who's good.
Don't worry, you'll get this figured out. And you'll learn some invaluable stuff in doing so. Hang in there and keep the faith. And for God's sake don't go back to drums. We make fun of those guys on this forum.
