When I got my first bass a year ago, I just Googled for "How to play Bass Guitar" or something, anyway, it lead me to a site that taught me the most basic thing: Stretching.
Practice pentatonics or chromatics with 1 finger per fret. If it's too hard on the 1-2-3-4 frets, go higher a bit, to the 5-6-7-8 frets as a beginning. Then slowly go down back to 1-2-3-4.
