This is a very good list, covers pretty well everything you need to get the job done. But to make it more pleasant, I'd add the the following:
Hop Sock, for boiling hops in kettle but keeping them out of the way for draining into fermenter. I think I put instructions to make one of these in teh "Technique" forum
Auto-syphon: no more stuck syphons
Ball valve, weldless bulkhead, SS braid in kettle so that you can just open the value and let 'er rip into the fermenter
A spatula is good as a mash paddle, actually I prefer it to my purpose build mash paddle since it is larger and sturdier
It's also wise to have several fermenters so you can have a pipeline such that you never run out of beer and its always in optimal condition.
Hardware for yeast starters is good too.
