Hey Rich-- I haven't climbed in the Oetztal alps, but have climbed a number of times in the Suedtirol on the other side of the Etsch valley, i.e., Cortina, Sellajoch, Groednerjoch. The B&Bs in the area are amazing, and the food/wine are beyond belief. This part of the Alps has some of the best cuisine in Europe, and that has made it a destination for lots of Germans and Austrians in particular. I would pick up a bit of meatball German if you don't already have it, although you will need some Italian if you have to deal with many authorities. It isn't Germany or Switzerland, let alone Chamonix, and many (more like most) folks won't speak English. The one guide I can safely recommend is the Berlitz traveler's guide to German or Italian. The area is gorgeous-- these are the mountains that Messner has chosen for his retirement!
Bozen is definitely worth a rest day for the market, Waltherplatz and shops and to see Oetzi. If the weather turns bad, you can drop down to Garda for sport climbing.
