Okay. So it's been a while since I've touched my bass or my acoustic guitar in any seriousness (essentially 2 years in the bass's case), and I really want to give this music thing a decent shot.
The thing is, I'm not really all that keen on starting from the very top again. I have some basic (call it 'fundamental') general music knowledge, and some prior experience playing, so I don't want 'the first string is the G string...', sorta stuff again. I am now a starving first year university student (undergraduate in computer science, btw) so lessons or even new books (and definitely new equipment!) are completely out of the question.
I'm thinking I would like to start at correct finger positions and everything, then move onto...what? This is where I am unsure; should I move onto standard notation - just try and pick basslines out of songs? What worked for anyone in a similar situation to me?
FYI, the styles I'm leaning towards is good solid rock bass with a healthy (make that very healthy

) dose of groove/funk. (And in terms of the acoustic guitar, I'm going for folk - think Bob Dylan/Nick Drake sorta thing)
Thanks for any advice - I want to do this right this time.
