fuzzb0x gave you a good tip on having a set up done..Poor playability could turn you off to learning. Definitely made it harder to enjoy.
1 Start with core lesson Fundamentals 1.. How to select guitar is here..
2 Get a tuner. The newer clip on styles are great in my book.
If the guitar is a brand new purchase the dealer may set it up for free..
You may want to get some lesson under you belt and decide what type of music you are aiming to learn.
To me, a lot about guitar is the feel.. So learn some chord and scales, a few easy songs and then think about what you want out of a guitar.
Good luck on your guitar quest..
