You need to get the 650 racks. That much I can tell you. The rest just depends on what you like. I like the aluminum boxes, others don't. Look at the luggage thread to get ideas.
Tool Tubes depend on what racks and luggage you get. Some will be easier to mount than other.
I have Happy Trails panniers, a lot of people on here do also, and I really like them.
