Yeah the Chaingun fittings are cool, same as any other compression fitting, just looks really cool, no functional difference.
 
Yes that is the B I was mentioning, actually I got the unthreaded version, with the standard hose barbs for 1/2 inch but I am not seeing it now, and they used to be cheaper :/
 
The G1/4 tapped should be good as well, never used that type, mine are all the barb variants.  Also, make sure you power it off of molex not a controller, no need to put it on a controller.

That's a solid compression fitting, but if you are going with 1/2ID I would STRONGLY recommend going with 3/4OD, thicker tube wall will make it much more resistant to kinks, especially as it gets older.

For the coolant, I wouldn't bother, Distilled water and a biocide and you are good to go.  I have added a few ounces per liter of a corrosion inhibitor but that's about it.
This is a solid biocide http://www.sidewindercomputers.com/peptpcobi1.html and was tested with the Feser coolant additives.

Yeah, you will need 10 for that, and BTW, those are sharp looking, little too flashy for my tastes, but but nice.

Hmm just now noticed that the pump is tapped with 1/4, also saw the 3/8 version as well. Does that mean I cant use the Monsoon fittings above on the pump? Or will they? Are most of these threading sizes a standard? I haven't gotten around buying the pump and res just yet, just need my confusion cleared up so I can proceed forward in the next week or two to finish the parts.

Does that also mean I need to get another set of tubing just for the pump lols. Darn. More hidden costs lol. Good thing I caught on this early. I already got my 1/2 3/4 tubing in hand already.

Those Monsoon Hardline fittings are for acrylic tubing ONLY, they will not work with standard flexible tube. The last fittings you linked will work with standard 1/2" ID 3/4" OD soft tubing though.
 
Premixed coolant is a waste of money. You can get distilled\deionized water locally for ~$2 a gallon. If you want colored coolant, then pickup some Mayhems Dye, and you'll have enough to dye your loop a couple of dozen times. As far as other additives, I haven't used a silver kill coil or any biocide in my loops for years and I've never had any issues. If you want though you can always pickup either a silver kill coil or PT Nuke for ~$5 and it will last you forever. For less than $15 you can essentially have a lifetime supply of the best coolant with the only additional cost being the distilled water from your grocery store. 
 
My personal recommendation is colored tubing if you desire, and 100% pure distilled water with zero additives\dyes. It offers the best peformance, and you won't run into any issues with certain WCing manufactures denying RMA's because you had a kill coil\PT Nuke in your loop. 

Any recommendations for angled fittings? Like the ones sorta shown here on the reservoirs? And would it work in combination with the monsoon fittings that I will be getting or they are a direct replacement? Trying to figure out if I should only get 1 set of the monsoon and the other half angled? I'm starting out with one res, going to add a second to pair a set up like shown below probably next month. And or should I add any quick disconnects to the loop as well?

BitsPower also make several fittings in the style you were looking for, I swear by mine.
