I like your style. Keep on growing and learning. Practice practice practice. When your gf gets her SINK (she ain't never gonna keep up w. you in a Hobie LOL)encourage her to learn also, as you both will be paddling a lot together.
My own history is similar. In August 2006 I bought a 13'5" daytouring kayak and within a week was taking a rescue class much like the one you describe. And doing full controlled wet exits within the month. There's no reason to wait!
Go for it, there are many rescues and other techniques to learn. Get fundamental skills and have a blast building on them. Then you realize not only the full potential of your boat but yourself.
