carbon forks will be lighter, but they will not "smooth" anything. Not much rides better than a quality steel fork. You aren't going to save enough weight on a beautiful bike to matter. Get some good wheels and go with it. I think that deep-dish early 90's campy wheels like the old Shamal's are the sleeper dealieo right now.
Buy a TT-specific bike if you stay interested in Tri. You'll realize minutes right off the bat, and additional minutes when you get your position dialed in. Really.
