Update:
So after pricing out a beautiful combo of Gladiator Cabinets...

and realizing how little they would really get used...haha
I went and got a bunch of these at Zeller's:

3 wall cabs, 1 tall cab, and two base units with 3 drawers each.
I have also decided to go with the epoxy flooring. It seems to be a great balance of cost versus utility and good looks. I read the instructions and it appears that I will have to schedule it carefully between the day the workers don't need the garage and our move date!
As for overhead storage and the like, I will hang my kayak up with one of those pulley setups, and hang ladders and the like by the stairwell....will post pics soon!
