First my opinion on the bikes;
I have a Trek 7.5 FX, I got mine when the first model year. I was lucky to get one, they sold out quickly. I like it, it's fun to ride(after I put 25's on it), it shifts well, and has a wide renge of gearing. But, after a few years, I wanted a more. So, I got permission form shewhomustbeobeyed, and got a Specialized Roubaix. I also like, bordering on love, this bike. The position is similar to the 7.5, it has less road feel, but it rides better and smoother. Because it is higher at the head tube, you don't bend as far forward as other drop bar road bikes.
So, from my experience, I suggest you test ride the bikes on your list, and some drop bar road bikes. Then decided on one and pull the trigger before you change your mind. BTW you can also shop used to save some green.
My short history; My father, who started smoking cigars at 14, has had heart problems, ALL of his 6 siblings have had heart issues. From heart attacks, to bypasses, to a heart transplant. I figure this puts me in the barrel of the ***. But I have had an active lifestyle since my early teen years. Running, skiing, hiking, climbing, and of course cycling. Hopefully, this will keep me a bit safer, or make the recovery quicker when it does happen. I do have some bad habits, I don't really watch too much what I eat, and go through periods of inactivity, and like a beer or cocktailor two now and then. I tried smoking in college, but didn't want to spend the money to smell like an ashtray all the time. Still can't understand why people do it.

Good luck, and Enjoy the Ride.

BTW, that LeMond is sweet, don't ever sell it.
