No kegs, at least not yet. That's a goal of mine down the road, but not a feasible one while living in an apartment. Once I have a place of my own, though... just wait!
Doing some tweaks with online calculators, and it's looking like 5lb/1lb of the extract is approximately the right amount for a beer that'll come right about where I want it, but the calculators I've seen don't really know how to account for juice.
