As a fellow guitar player (I actually played at a wedding and funeral in the space of the last 18 months) I feel your pain here.
Never bothered with electric though for some reason.
Still...once you get these annoying issues ironed out, it will be all plain sailing. Except for the painful fingers, callouses, frustration, that voice in your head saying 'seriously, just fucking give up, why are you putting yourself through this?'...etc.
Btw - I'm sure you have all this stuff sorted, but I recommend guitar.about.com for beginner guitar lessons. The site looks like it was constructed in about 1996, but the info is all solid and totally free. There is no filler there whatsoever - just all the basic info you need to start learning, and step by step lessons.
It's exactly what I used to teach myself guitar in 2001 and haven't looked back since.
