If you buy an AZTA membership, you should get access to the databook, which includes lots of good info on resupply.
The best resupply between Patagonia (mile ~50 if memory serves) and Oracle (mile ~200) is La Posta Quemada Ranch in Colossal Cave State Park. Check to see if they still accept packages. It's directly on the trail, which is hard to beat for resupply.
There is also Summerhaven, but it's only 15 miles from there to Oracle. There is Vail, but that's off-trail a ways.
