What do you think of the OC potential for my CPU in this system? Do you have any useful criticism of my watercooling loop to offer? Should I also watercool my GPUs to?

1) overclocking potential varies cpu to cpu.. that said short of saying you're going to delid the cpu, you certainly seem to be doing everything you can to make it work~

that said, there are very real limits to haswell overclocking. no matter how good your cooling you'll likely be limited by the mediocre voltage regulation on the chip itself. this type of build would have saw a much better payoff on a sandy bridge or ivy bridge system. understand... the vrms on the chips helped intel save power, they're quite good for low power draw and low power states, and...

~unless you get a dud chip (and there certainly are dud haswells out there) and you're willing to delid it, you should get up to 4.7ghz with this build. you know you got a dud if even after deliding the cpu won't stabilize over 4.2ghz... there ARE chips like this out there, that's not an intel, haswell or amd only problem. it's the nature of the overclocking beast.

2) not going to page through all the parts in your loop... but as long as you're not mixing metals you should be ok (no aluminum and copper parts in the same loop). if it's a copper radiator, make sure it's a copper cpu block.

3) i don't think your psu is nearly strong enough to run 2 heavily overclocked and water cooled 760's and a heavily overclocked haswell at the same time. unless you plan to up that psu to a 900W unit, there probably won't be any point to adding a 2nd loop and water-cooling the gpus too.

Also, I am still in luck as I have not bought this build yet (short of one 760 and the HDD [Which came from another PC]). So any recommendations would be great. Also, would getting a HX1050 instead be a wise move if I plan to WC the GPUs?

As long as the chip is in spec - http://ark.intel.com/products/80811/Intel-Core-i5-4690K-Processor-6M-Cache-up-to-3_90-GHz - then no - you can't rma it. But all of them should at least get to 4.5GHz. But you don't need custom cooling to do it. A Noctua air cooler or a H60 would be fine. An extra $300 of cooling might get you an extra 0.1GHz.

For 2 x 760's in your pc you need at least 700W. The HX750 would be fine. Its a good quality power supply.
You can check your wattage by plugging in your pc details to http://extreme.outervision.com/psucalculatorlite.jsp
