The garage looks great! you should add a baseboard to it to give it some really nice definition, I have pictures of garages before and after with baseboard (rubber variety), and its cheap to do!
Now on the epoxies, I've applied epoxies to a few garages, and haven't been overly impressed with them. They seem to lift rather quickly, which make it hard for me to recommend to people to go with an epoxy.
My personal opinion is to go with a floor covering, as your guaranteed a lot longer life out them then the epoxy. As mentioned above the Race Deck is a great product with a 10 year warranty. Another product I like a lot is the G-Floor with a 5 year warranty.
Now the Race Deck, and the G-Floor are both more money then an epoxy... but when you factor in 2 coatings and the prep work to removed the first coat in a few years, that pays for a flooring hands down!
Now this is just my 2 cents....
