If you have everything but the faucets, there is not much to do. You'll need the faucets, shanks, and end nipple. You can buy the whole shebang here, or piece them together individually. Check E-bay and craigs-list as well.
I just did what you are doing recently, it was pretty simple to do.
I removed the shelves from the inside of the door first. The shanks were a bit long to fit all the way through the insulation so I cut out the existing insulation in a section, installed a 1/4" backing board and put some new insulation in. I'll post some pics if you need them.
