Thanks to everyone who has contributed to this post, my belt and pump replacement almost went entirely without a hitch thanks to these thorough write-ups.
I just wanted to add a couple of tips I found through error in this process.
1. Look at this video to have a tour of everything you will encounter if you have a 647 engine.

The sound track isn't fantastic but overall I give it a solid B
2. If you touch a hose I would recommend replacing it unless you know it has been replaced. I replaced all hoses but one and the only one I didn't replace had a pinhole in it due to a lame clamp design/hose being bloated and worn out. Had to wait for a new hose to come in from Europarts to be able to go on long drives....
3. The torx on the water-pump pulley are loctited I believe. I strip the head of only one out before blasting the others with a torch. After the torch they all came out easily.
4. Replace the thermostat...mine was pitted on the gasket flange and definitely would have begun to leak soon. Taking the oil filter out and covering with tin foil to pull away the fuel lines makes this simple.
That is it folks, thanks for all the help.
