Destroyed an iPhone 4, trying my hand at DIY...

I've got an iPhone 4 CDMA that's taken a beating. It can still power on and pick up a carrier signal. I've looked at the teardown guide from iFixIt but am still having issues ID'ing the parts necessary to bring it back into working order. Besides the front display, rear glass panel, and home button, what else do I need? Here are pictures of the damage. Any help would be appreciated.
