I came in here expecting pics!
Guess you want to make sure everything is 100% beforehand...Not a bad idea. For barbs you'll need a pair for each block your installing, a pair for your rad, and a pair for the res (unless you want to use the plastic swiftech ones...). Your pump has built in barbs (unless your using an aftermarket top).
Only thing I would change personally, is go with UV tubing for the same price, and run distilled. You'll void your warranty on your res. by using feser one, and can possibly weaken the acrylic.
Other then that you look good 2 go!
I recomend the UV Cathodes too, I like them alot more than just blue lighting. Heres a pic of my setup.
