Most Excellent!!!
I like the idea of putting the garage door on the load bearing side of the trusses and running it up to a cathedral ceiling, neat way to get it out of the way. Bet the header above the garage door was huge/steel to carry the trusses!
You'll love your epoxy floor, I love mine as it has proved to be nearly indestructable. One hint, if you can stand it, do not put anything heavier than you in your tennis shoes on it for 30 days, give the epoxy a chance to cure rock hard.
Also love all the lights! I have 14 in the my shop, 9 over the shop area, and 5 over the car parking area.... you can never have enough outlets or lights!
