I think a 72" should be quite reasonable for a 3320. You definitely want it wide enough to cover your wheel tracks.
Scarifiers will have no trouble with rocks, but will generally pop them out of the ground, so they will collect in the box and be moved with the dirt. One thing to watch out for is that if you hit a big rock, or something else immoveable, hard, it could damage either the implement or the 3ph. Best way to minimize this risk is to operate slow. Draft control also helps, but I assume you don't have draft control on your 3320.
I should add to my earlier post - I have nothing against Worksaver and would gladly own their implements, but only at prices somewhat less than Woods. I think Worksaver is good to very good quality, while I think Woods is excellent quality (excluding their few bargain lines like "Heritage").
