start with an electric acoustic, and try and find simple/repetitive songs that you like and download the tabs for it
as already stated, id start with nirvana as it will have both chords and a simple solo you will recognize, and that will help you fix the problems with your fingers while holding down the strings
then memorize and practice beginner guitar chords, and during this start learning/practicing scales:

this is indian, but you'll see on the tab chart how a scale actually works.. once you have done this for a few days, pick some good blues songs

and this will show you how scales are used to play music/pracitice etc
good luck!
