There's been a lot of great advice already on this thread - I'd add this: Pick really easy songs to start. The idea is to get some early 'wins' to keep your motivation going. Memorizing the lyrics and the chords/bass line first so you don't need to read them really helps. Ramones, Weezer, ZZ Top, CCR, Tom Petty, Neil Young come to mind as bands that have lots of popular songs with easy lyrics and vocal melodies, and basic quarter-notes-on-the-root bass lines. Cinnamon Girl is a really great song that's super-easy. Moonage Daydream by Bowie is another good one - a bit trickier in the chorus with the descending bass line that doubles the backup vocals, but still doable and gets easy once it 'clicks'. Save the Stevie Wonder/Jamerson songs for a real challenge later once you can do the simple stuff.
