What are some of the recommended performance upgrades to increase horsepower and torque in a 4.7?
You need to spend some time reading here on the site and see what these other guys are doing to their 4.7s. It is amazing the time and money they involve and the power they can get if you have both the time and money. We have a FAQ section at the top of this forum.

what Weed said. I've been considering the superchips programmer.. They say 40ish HP and i forget how much torque.. Module is only like 300 bucks which is pretty sweet.
I'm sure most will make mention of "the big three" - Air intake, exhaust, and a tuner....(not necessarily in that order). Good luck!
