In reply to vberg:
Basic crevasse rescue kit, a 30 or 40m rope and 1 axe are all you need though I'd also wear a helmet if only for the approach in the dark when people above might knock stuff down on the scrambly bit, though the risk is minimal.
There's a couple of neighbouring peaks to the right of Gran Paradiso, La Tresenta and Ciaforon which make good acclimatisation peaks, save you doing extra hut walk ins. The routes are obvious, what you see (from the VE hut) is what you get, just follow your nose.
