Any of the US published model aircraft magazines:
AMA's house mag 'Model Aviation': http://www.modelaircraft.org/
Flying Models, a great magazine which covers all of aeromodelling, not just RC: http://www.flying-models.com/
'Radio Modeler' is now defunct, but its plans service continues: http://www.rcmplans.com/
'Fly RC' often has smaller models available free online: http://www.flyrc.com/
Naturally, there's rip-offs all over the web as a whole and E Bay, for a variety of costs.
Most magazines include some level of description as to what a model's designed for. Sounds like you need 'trainer' high on the shopping list, followed by a local club, AMA membership and finding yourself an instructor you get along with.
The alternative is teaching yourself to fly, in which case your 'instructor' will know precisely the same about flying RC as you do
Good luck, welcome aboard.
