mtnbke, You might want to PM rccardr or pastorbobnlnh, to name two ST owners for how to modernize/upgrade. I have a 3.0 touring frame I rebuilt earlier this year and it's a slightly different design so I can't provide particulars about the ST.
These bikes do seem to update very well so you have plenty of options. Bar ends are a nice system to move the levers to the handle bars and look appropriate on a touring frame. Tektro dual pivot calipers will improve braking and Harris Cyclery is worth looking at for a wheelset.

PS While I think it was on a bike that was stolen, I'll see if an old Cannondale water bottle cage is still around.
