In reply to BStar:
I was in the Stubai valley last summer, its very well set up for the activities you want. I picked up a free via ferrata guide from the tourist info office where they also have good, regularly updated weather forecasts. I also got a good map from there which had info on huts and cable cars etc.(and much cheaper than the Alpine club maps).
The Via Ferrata guide is in German but you can mostly work it out. They range from short easily accessible ones, to full on, long serious mountain days but all seem to be well equipped and quite new.
There are also a few rock climbing areas (sport crags) shown on the map and with route info available from the nearest hut.
One point about Alpine routes to note however is that the glaciers have retreated a lot in recent years. We were using the Diadem Eastern Alps guide and found that the route descriptions were all out of date. We had to find alternative routes or take variations to get onto the routes because of retreating glaciers. It would be worth checking locally or on websites like summitpost before you head off for a route.
