moremoney: you will always earn respect with even the most jaded forum-ite as you've actually put some effort into identifying what you may (or may not) need. 
The MCP655 will cope with three blocks without a problem: ever since that pump hit the market (together with the DDC), achieving the right head ceased to be too much of an issue. I would actually suggest going for a DDC-Ultra with the reservoir top as it is smaller than the 655 and you can pop whatever barbs/connectors you want on it. And reservoirs are simpler to use than T-lines, but that's just my opinion...
If my reading is correct, you may probably well be fine with a dual TFC radiator: they seem pretty damn good and should to the busiess for your hardware. Believe it or not, but your components aren't the hottest in the world (I can't see a Core i7, P4D or Athlon 6400 in there, so...) and so should be served pretty well by the 120.2 rad.
Blocks? as I've posted in another thread on here, you have to try really hard to buy a rubbish one, nowadays. Whilst Thermaltake continue to be renowned (unfairly or otherwise... you decide) as poo, there are a lot of blocks out there that will serve your purposes without hiccup.
Barbs? I believe the Swiftech pump has 1/2" barbs, so you may well want to go with them throughout the kit, together with the 7/16" Masterkleer tubing (no apparent need for hose-clips using this stuff - not used it myself, so I can't comment). However, with modern WC pumps, most rigs will get away with even 8mm ID tubing, bringing in the range of compression fit connectors. Having used these myself, they seem fine and so much less of a pain than barbs and hoseclips. But that's my personal preference. 1/2" will always look cooler...
And for the love of all that is overclockable: do not waste your money on feser coolant. It is pointless. Distilled water with a little Zerez/Purple Ice will do the same job and be much cheaper. And besides, if your system leaks, you haven't plumbed it properly anyway, meaning you shouldn't have started watercooling in the first place.
