I like the strings low to the neck, that's why i prefer playing on electrics rather than acoustics.
Back to the subject -
Good computer program is Guitar Pro
www.guitar-pro.com you can download songs from
www.mysongbook.com and use that program to play em, then you can learn them, it actually plays them for you so it's WAY easier
Also, look into getting a personal trainer, they can help you get the skills a computer program cannot teach.
Either acoustic or electric is fine, i prefer electrics as i find them easier to play with, the strings are thinner, the actual size of the guitar is smaller, but it is heavier, there is also the fiddling around with wires.
Stick with it, i am lucky to be a naturally talented musician, but even if you aren't, you can still become an excellent guitar player, practice makes perfect, just stick with it.
Good luck,
Adam.
