Thanks to all for the information, advice, and encouragement. I went to my LBS yesterday and got fitted for a Trek 2.3. The guy spent over an hour with me on trainer and trying 56, 58 and 60cm Treks. This was after he adjusted my MTB cleats to the right position. We settled on the 60cm after I had ridden the 58 and 60 on the roads behind the store. I just felt more comfortable with the slightly more upright position. And if I need to I can always lower the stem a bit.
No excuses now, have to get my fat a$$ out there on the bike trails and just ride.
