Recently changed the stock calipers for Ultegras. Fantastic difference. The stock ones were absolutely dire.
I'd stick with 23mm tyres for decent clearance - at least on my 2007 model.
If you really want cantis or discs (and I would), then get a Pompino F&F for cantis, or try and track down a Singlecross (same as Langster but CX clearances & canti brakes). No idea what to recommend for discs though.
