As mentioned below, I would try AP marks, Armor yellows, Scaling MR blues, and AP quints.

Use Offensive masteries, as you'll need to squeeze every ounce of damage that you can. Ahri isn't really ideal in the jungle, but if you can pull it off your ganks should be decent, provided you're good with your E.

I think I'd try starting with Hunter's Machete + pots. If that didn't work, you'll probably need a cloth armor + pots. Being a burst mage, she tends to have low resistances and low damage output early game, which is going to cause considerable problems in the early jungle. After a few levels it should pan out well enough though.

I would say getting the Rend jungle item early is going to be of the utmost importance.
