Sorry to hear the deal wasn't real - that's a great price. I would have said to do something about the seat height to bar height difference or your neck will suffer big time after you've been riding a few hours.
I do a lot of long distance riding, an occasional 24 hour race, 1200km (750 miles) timed events, etc. For your height and inseam you'd probably want to go with 170 or 172.5mm cranks for spinning purposes.
For the lowdown on bikes and a great collection of cycling enthusiasts who don't think $4k or more is too much to spend for something without a motor drop by the Bicycling magazine forums and sign up.
