6' tall and banging your head, just sounds like "yuck" to me. more so once you get lights installed. and then non stop glar of lights right into your eyes. if you could forget the deck, and say just build a garage extension. with a taller ceiling.... 7 to 8 feet high or perhaps a little taller.... the area would more likely be more inviting. and not have head aches, from lights blinding you.
or when you walk out onto deck, you have to take a couple steps up onto the deck as you come out the door. to give you more room underneath.
or perhaps digging down further, to increase your height. and installing a french drain, and sump pump. to deal with water.
The drains are something to consider if you are removing 18" ?? I assume your lower floor is a slab. If I picture it right, there is some concrete wall that comes up above grade? In any case, there should be an existing perimeter drain around the outside of your foundation. You don't want to let frost get down to that by removing too much soil. If you were building a closed in space, like a garage I don't think it matters, but an open shed-type area would.
Sounds like you haven't really settled yet on the plan, but its good to ask what-if questions along the way to avoid surprises.
If your asphalt drive is fairly flat or just a minor slope, and not real long, you probably won't need tractor chains. I used to have an almost flat asphalt drive in Wells and I never had a traction problem with R4's, did have the backhoe on, so that added a lot of traction weight. If you get into icy conditions on asphalt, sand works well, it's cheaper (or often free in small amounts at the town yard) than chains, and no damage.
