Hello Jonathan,
Nice to meet you and welcome.
First of all, you're in luck as we have a Youth program that you may wish to take advantage of. Go to this link if you haven't already taken a look at it;
http://www.thearma.org/Youth/Youth.htm
Secondly, I'm sure we can arrange to have you meet the guys up in Seattle area, one of whom lives in Issaquah.
And thirdly, read. Read everything and anything you can get your hands on that is related to the subject, but my recommendation is just to start here, right on this site. There is a wealth of information and basic material to get you started. From the ARMA Method to the Practice tips section and the videos and... well, so much more.
If you can buy some books, I'd recommend the some of those written by our members which I've linked below. There are many other fine reading materials, however these three cover some of the fundamentals that are so important when beginning, and continuing afterwards, in this endeavor.

Hope that helps get you started, and maybe we'll see you soon. Oh, and by all means get yourself a decent waster, if you don't have one already. It is an essential piece of the puzzle and you really can't do much without one.
Cheers!
Ken
