Matt,
You are getting good advice here. I would only add that it may be a good idea to wait until you talk with your instructor and see if he/she has an extra trainer you could borrow, what type of trainer cord you will need, extra field equipment etc. I'm not telling you to be a free-loader. I just know how charitable people in this hobby can be. In the past year I have given-away 4 transmitters/receivers, 3 planes, 12 servos and numerous props, glow-plugs and fuel.
Get an instructor and make some friends at the field. You would benefit from the experience like most of us have.
Welcome to the END of 'Free Time' and 'Disposable Income' as you knew them.
Good luck and HAVE FUN!!
