I find it hard to believe that your current 50/34x12-28 setup doesn't give you low enough gearing. I have a 50/36 with 12-27 and it gets me just about anywhere. Perhaps you should try your new ride out for a couple of months before tinkering. You might find that it gets you where you want to go just fine, and you'll save money and time.
But be this as it may, if you are dead set on tinkering, Shiftmate is probably the quickest and easiest solution, assuming you already have the XT rear derailleur. Otherwise you can just get a Campy mid or long cage derailleur instead of the XT and nix the Shiftmate altogether. But there is one caveat: you didn't mention what hubs you have. If you have Campy hubs, it may be a moot point. A SRAM cassette won't fit on a Campy hub. And as far as I know neither Campy nor Miche makes a Campagnolo-splined 11-32 "mtn" cassette. I believe the lowest Campagnolo-splined cassette is a 13-29. However, you might check American Classic. They might still make a Campy-splined "mtn" cassette in the 11-32 or 34 range.
