Supergolom, you might want to try some kind of method book. There are a lot of different ways to go here. I'm guessing that you play primarily pop/rock or jazz. I think that the latest edition of Hal Leonards Bass Method, edited by Ed Friedland, is a good starting point.
The book comes in three progressive volumes and has CD's with which you can play along. The method uses mainly standard notation but does include some tab. It also touches on many different styles. Good luck.
