Here is a program called PowerTabs for writing, reading, and actually playing guitar tabs. It really helps you learn the music better than an ordinary tab because it goes through the entire song and highlights each note in red while simultaneously playing the notes in a MIDI file. Perfect for getting the timing down correctly and figuring out the complete tab when songs have multiple guitar layers, which I find hard sometimes.

 

There are a bunch of tabs at powertabs.net in the correct format used by the program. Otherwise, you can try to enter tabs yourself, and play around with the notes and timing until you figure out the song correctly.

Pretty durned cool.
