How about
: don't waste your time here trying to find shortcuts that will make you a good player

. Practice!
And also: I like this program called Guitar Pro. It has separate tracks for all instruments, and volume control for each track so I can mute the bass player. I'll just download the songs I want to (
http://www.mysongbook.com), and I can play along, slow it down or speed it up. Better then playing along with the recording because if you lose the rhythm, you can't relate to the bass on the record and have to find a way to 'get back' into the song.
