I have the water pump currently removed and replaced and just need to get the new thermostat in. Me and a buddy spend 4 hours yesterday cussing BMW. I will post when I have it complete.
Is it tough, yes. Can you do it, Yes I am by no means a mechanic and my friend as well. He does a lot of work on his own 335i and was nice enough to help (mainly to get another set of eyes on how to do it). Its all done from under the car but we actually were able to pull the Water up up the top rather than out the bottom.
I will post when I am done and if anyone has any questions please let me know.
I am also doing the oil filter gasket and coolant gasket at the same time.

Got it all finished up. It was a PITA but nothing anybody couldn't do. The hardest part is getting to each of the hose clamp screws but when you put it back together you get to angle the screws how ever you want to make life easier. Took 3 hours to get the pump out, about 2 hours to get the pump and thermostat back into the car and another hour or two to get everything closed up. I spent a total of 10 hours doing the following
Water Pump
Thermostat
Oil Filter housing Gasket
Oil Filter housing Coolant Gasket
Oil Change
The honest hardest part of the process was getting to the screw on the oil filter housing that was under the intake manifold as you have to remove the manifold (which you really just need to separate it from the engine about an inch.
