Try some Black Sabbath songs.

If you ever come to a part in any song (by any band) that you think you can't play, don't be discouraged; just take small parts and practice them at a slow speed. Once you feel comfortable with one speed, try it a little faster. Most people recommend a metronome for this purpose, but I've never felt the need for one.

A good free program to learn songs with is called PowerTab. It's a guitar/bass tab program that uses MIDI to play songs back while you try to learn them; it also has a built in metronome. While this program and others like it make it easier to learn songs, you should still try to figure out stuff using your ear.

I haven't actually tested this, but I thought about a technique to help with ear training. Learn all or part of a song using a tab, then stop playing it until you pretty much forget how to play most of it. Listen to the song again and see if you can figure out how to play it, by using both your ears and your memory.
