Hi,
Even if I'm italian, I've never done some bouldering in the Dolomites. Anyway I probably have some info that could be useful for you. The most famous location to do bouldering in the Dolomites are Val di Daone (just above Lake Garda, next to Arco) or Val Gardena - Citta' dei Sassi.
Anyway there is a german website quite useful with a lot of topos of places where you can do bouldering in the Alps or Dolomites. Just click on the link and then a google maps of Italy will appear. If you click on the symbol located on the place you are interested, a link will appear with the description and the topo.

Hope to have helped you.
