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.
