Hey, just trek down to the local license supply store (i.e. walmart, kmart or local fishing store). They'll all be able to sell you a license and they'll also have free booklets w/ species pictures, legal lengths, bag limit, and seasons for harvesting.
The only catch is you have to keep up on changes to the regulations throughout the season. A quick check to the local equivilent to the DNR or fish and games website will keep you abreast of all of that.
Last thing is to avoid buck fever b/c the 14" cabezon looks like a 20 incher underwater. Get a good reference before you shoot and have fun.
