In reply to Sunny Howard:
Piz Ciavazes is well worth a look as well - quite easy access. I'd heartily suggest looking at some shortish sport multipitch before getting stuck into dollies trad multipitch - mainly to get used to the rock and length of routes. By doing a sport multipitch you can get into the groove a bit, and acclimatise (the altitude isn't crazy high, but can still leave people short of breath the first couple of days)
Frea (Gardena pass) and Sass Dlacia (en route up to Falzarego pass) would be great places to check for short sport multipitch (as well as some great single pitch)
1st Sella tower would be worth a look for sure - easy access and easy, shortish trad routes.
