Here's my opinion, which is a lot of personal preference, so you can take it or leave it, and I'm not trying to say it's the best or only way to do your loadout.
Also I'll be assuming you're using ehobby as your only source to buy from, so I'm picking from their selection.
1) SOF guys usually have a lot of play in what weapon system they'd like to use. I'm sure if a CCT was dead set on using an M14, he'd be using an M14. But usually they're attached to other groups, and with the weight of the batteries and the importance of their primary job in commo, they're usually carrying the smallest weapon possible. A shorty M4 would probably do good enough.
2) Why'd you get CB!? Get OD, and rejoin your PLA/CAG brethren.
3) I like the idea of the HSGI TACO pouches but they're very bulky and I don't trust how loose they are. I'd probably get a loadout for either an M14 or M4, but not make it easily switched.
4) The mag pouches you linked to are shit. I don't like the thick flap on them, and would either get shingles or closed top pouches, which are a lot lighter than that large chunk-flap of cordura hanging over top. I'd suggest something like this:
M14 Loadout:
I'd get a row of the .308 pouches in CB from Tactical Tailor + an MBITR/HAM/Large Radio Pouch on your non firing side. TT's mag pouches are some of the best I've ever used, and they are a lot lighter than the ham fisted 1000d Cordura ones. I like the two mag pouches, because you can put the flap between the two mags, and you have basically a two mag pouch with the front mag being a ready mag, or if you're in transit on a bird or you're rolling in the dirt, you can completely close them up for safer transport and less dirt in your ammo. They are also large enough for other items in case you have to adapt (other radios, batteries, medium sized items).
Then put your radio pouch on your non firing side so you can snake your antennae up through the shoulder or along the side and up the back.
I would get the back plate just for the plate storage as CCT and most soldiers wear front and back plates minimum (I'd even suggest side plates). I would put one of two things on the back. Either get a large dump pouch on top and a side-sitting camelbak (Israeli / MOUT style) or I'd get a single Camelbak bladder holder. I recommend against the built in backpack, because it's very hard to get into if you're using it, and it's a lot better to have a light assault pack that you can throw on and off to mess with manpack radio settings or get to items you need if you're alone.
5) RRVs were meant for recon or for a very empty back to throw an assault pack or ruck on, depending on mission, with at least one hard water source on the left or right. I'd put a canteen/nalgene on one side, and an IFAK on the other. At the recon school I went to a year ago, the Ranger guys were using them with canteens on the sides and no back plate, preferring to store a large ruck on their back and not crush anything they put there.
6) Since it looks like you're going M4 anyways, I'd go with this:
M4 Loadout:
I'd get a complete row of single shingles on the RRV, then have a few pouches on the front of that. I would put two of these on the front: http://shop.ehobbyasia.com/combat-gears ... -drab.html
OR, instead of using shingles, which I am personally not a fan of, I'd get a slimmer profile and have the radio on the non firing side and fill the rest of the front up with 4 or so 2-mag pouches. These are the perfect size for smoke or two mags. And like the other mags, putting the flap between the two mags makes them snug and the front mag becomes a shingle. Also they're thin profile (3 mag pouches are too much) and they're very light so the pouch whoring won't weigh you down: http://shop.ehobbyasia.com/combat-gears ... er-fe.html
I'd put the radio still on the non-firing side, then get a few flat utility pouches in the front: http://shop.ehobbyasia.com/combat-gears ... pouch.html
7) I like keeping the bib down and riding the RRV up almost like a chest harness and keeping it very high. Putting the weight on the lower half of your ribs instead of on the soft gut really helps with running with a full combat load and the tendency of gear to knock the wind out of you slowly as it pushes down on your diaphram and gut meat.
BUT I do like the use of the admin pouch and I'd suggest getting something like this:
http://shop.ehobbyasia.com/combat-gears ... panel.html or
http://shop.ehobbyasia.com/combat-gears ... -drab.html for a place to store papers, ID, pens, SOIs, compass etc. I really like my Condor Admin pouch which is a pretty close replica of the TAG one.

That long pouch you posted might be alright on the side, but long pouches annoy me and I've never had luck with them being practical.
9) And of course,
Dump Pouch:
I really *hate* the rolly polly dump pouches. In a real situation you might be dropping random gear into your dump pouch and using it for more than just 100% empty mags (A tactical reload of a half full mag) makes a rolly polly flop around and they are noisy and cumbersome, whacking you every step when you're running. I like dropleg dump pouches and I'd suggest this one, which is pricy, but these things are worth their weight in gold: http://shop.ehobbyasia.com/combat-gears ... pouch.html
