Welcome.
I'd only make the step to AG if you've ironed out your cold side technique, however a transition to steeping grains and hopping is an excellent run-up to starting AG on the hot side if you've not done it already. Kit + Kilo sets (tins of concentrated hopped extract) never seem to produce particularly good beer, and tend to carry with them the tastes that people associate with "homebrew". I've produced some excellent beer with a full-boil extract method...
All you'd need on top of your current setup is a large (8gal or more) boil pot, and some hop/grain bags. This assumes you have access to a stove which can put out the necessary heat.
Either way, come to the meeting on Saturday and say hi.
