Firstly. Woot. Guitar is fucking awesome.
Whilst I am still a bit of a noobie myself, I think the way I have gone about it has worked pretty well. What Sniper says about not getting a steel string is kind of
legit. I only say kind of because to be honest it's not that painful to just ride it out playing steel string 'til you get your calluses. It doesn't really take that long to get 'em.
But still get a nylon string I think because classical guitars (this is the type of guitar that uses nylon strings) naturally have a fat neck. Fat necks are harder to play because your fingers have to stretch further for certain chords, like your C and G and barre chords are going to be a bit harder on the classical fat neck and I think this actually makes you really good a chords.
I started out with an old classical guitar and when I went from that fat neck to the slender neck on my steel string, it just made the steel string feel SUPER easy, and I realised how the classical had helped me get some good dexterity and strength.
The other benefit is that you will be able to find a pretty decent classical guitar (yes, Yamaha is probably your best bet here) for a pretty sick price. Also, if you actually want to play some classical (which is pretty fun imo and the reason I fingerpick), you have the perfect instrument for it.
Also I must echo what Kade says about the guitar stand. They are cheap and you can have your guitar sitting right next to your desk within reach at all times. Nothing beats playing guitar during those slow waits between games on bnet sometimes :)
I have learned a LOT from this guy, man. His teaching is very clear and methodical, and you can work your way through his classes in order of difficulty. Really, really good website. And free!
