Learning to properly set up action (string height) and intonation on your guitar are pretty basic things. It isn't rocket science. A good and worthwhile book to have is Dan Erlewine's How to Make Your Electric Guitar Play Great. Buy it new so that you'll be sure to have his measuring tools that he includes in the book. Tools to measure the radius of the frets and tools to make sure that your string height matches that radius.

When I purchased my first electric guitar I loved it, who wouldn't. After buying this book and properly setting up the guitar I loved the way it played and sounded even more. It was a world of difference. Very rarely do you get a guitar "off the rack" that's ready to go.
