it does depend what you're playing, but i always just learnt solos that i like by using tabs and listening to the tracks. i think you're far more likely to stick it out if you're playing stuff you want to learn and not just chords and scales (which can be extreamely boring). as you learn solos and riffs you soon pick up chords.
you might want to start with something you know really well so you can sorta follow it in your head as you read the tab (if that makes sense), but dont try to do things like "eruption" (like i did in the second week of learning) because you'll probably just end up frustrated.
the first thing i learnt was the Bo Rhap and Killer Queen solos (hence the name), and i might suggest KQ as it is not that hard but sounds good and will hopefully give you a bit more confidence.
i don't know whether you're into that kinda music, so i could just be p*ssing you off with rather unhelpful advice :p
hope some of that rambling has been of help... if not feel free to say "bah! useless", but stick with your guitar! :D
keep on practicing and strummin! good luck!
