Have you got an Xbox or PlayStation?
I'd recommend Rocksmith if you have. You get a cable that connects your guitar (which looks very nice by the way - I just got a Squire Stratocaster before Christmas to learn on).
The game teachers you real songs, gives challenges to learn scanners and chords etc.
At the moment I'm working my way through about seven Oasis subs and about the same for Radiohead. It's brilliant playing along to songs you know and love. The difficulty increases as you get better at each song and it goes back a bit if you're struggling.
I've tried a few times to learn and this is by far and away the best imho.
