I'd keep Kennedy as your starter for now (and not just because Harris doesn't qualify at 2B yet) but if you have somebody you don't need that you can drop to get Harris and stash him on your bench, it might be a good idea. He's learned to hit, and Ozzie has said he's committed to make him into a great player, because the team relies on him (Ozzie's words, not mine). If he gets on base a lot, he could be a dark horse to lead the league in SB's. He's leading off for a very powerful lineup - Maggs, Big Hurt, Carlos Lee, Konerko, and Valentin - and should score plenty of runs. All he has to do is get on base. If he does, watch out.
