I've not been to Monza either, but would guess Ascari would be a decent option, 13-16 (do Italians consider 14 unlucky?) No idea if this is still current)...
13 would give you a decent view down the previous straight but does put a gravel trap between you and the track. 16 might be a better option. Check youtube and see if there's any videos shot from either, or anywhere else you're considering.
