You may have seen my garage thread already? You've hit on a lot of the features I'm including. In addition to what you list I included a bathroom, fridge (for beer!), and washer and dryer (for oily rags my wife won't let me put in her machines!).
One thing I would do different (actually 2), is make both doors a little wider. Mine's a 3-car design and I spec'd a 7 ft wide single door. Should have gone next size wider. The EBs fit through ok, but I have to fold the mirrors to get my full sizes in the single bay. It works but too close for comfort.
15 foot ceiling is more than enough, 12 foot should work with most lifts. Not sure what the extra 3 feet will cost you. Also look at your electrical service. I went with 125 amp. 200 would have been better but to get more than 125 I would have had to install a completely separate service. So I opted to live with 125. I just can't run everything at the same time! Install plenty of outlets, both 120 and 240 and put some up front near the doors so you can run extension cords easily to the driveway when you're working outside.
And, yes, I still need to add more lights!
