Yeah, I can recommend some changes. Your budget is $1300 overall? I don't know much about monitors, so I'll keep the one you selected.
That Cooler Master GX II power supply is alright, but for the same price the EVGA Supernova G2 750 watt is a far better choice, gold rated and fully modular.
Jonny Guru reviewed it meticulously and loved it.
The SOC Force motherboard is marketed for overclocking, but the
$170 Gigabyte Z97X-UD5H is just as good for overclocking, it just doesn't have physical buttons just for adjusting overclocking settings which is more of an enthusiast feature. Most people never need to make such adjustments, they just find a stable overclock and let it be. In terms of what the SOC Force doesn't have, the UD5H features an M2 slot, second LAN adaptor, and extra hard drive controller for more storage support.
You can see the differences here.
If you were interested in features like M2 slots, you could drop down to the
Gigabyte GA-Z97X-UD3H-BK ($130), Newegg has a promotion where the 4790K and the UD3H can be purchased together with a $43 discount, which would bring down the cost significantly. It's comparable to the other motherboards like the SOC Force and UD5H in terms of gaming performance and daily use, and not a downgrade by any means, other than slight differences and fewer VRM phases for overclocking. It's still an alright motherboard for overclocking (
4.7GHz attainable), just not the absolute greatest for liquid nitrogen enthusiast setups.
That RAM is grossly overpriced for the speed. There's cheaper, smaller, and faster 16GB 2133MHz Patriot RAM for $40 less.

Now, for your questions:
1. Typically, the thermal paste that comes with the heatsink is good enough for most people. If you want the absolute best, then
according to Tom's Hardware, Coollaboratory Liquid Pro ($15) is what you want. It idled at 32 degrees whereas Cooler Master idled at 38.3 degrees. That's $15 for ~6 degrees difference, although actual temperatures will vary due to installation, cooler, etc. Up to you. If you wanted better higher end cooling, look into a Noctua air cooler like the NH-D14 or NH-D15 - excellent performance, and Noctua's included thermal paste (NT-H1, 36.1 degrees) is pretty decent.
2. I assume you mean you'll only be gaming on the 144Hz monitor and not on both at the same time, in which case you will be absolutely fine. It won't matter at all what the second monitor is doing if the game isn't on it.
3. How many slots you fill up makes absolutely no difference, other than how much room you have to add more RAM in the future. Few people need 16GB or more, but there's no reason to go with 4 x 2GB instead of 2 x 8GB. RAM speed makes a tiny difference in everyday use, but some games and applications do see a speed increase. For prices today, it's very easy to find fast RAM (1866/2133/2400MHz) on sale at the same price as 1600MHz, so there's not much point with going for 1600MHz.
If you wanted to save another $60 off the cost of those parts, you could drop down to 8GB (2 x 4GB) for now and add another 8GB (2 x 4GB) or 16GB (2 x 8GB) in the future
4. No, you'll be fine. Few games require a CPU stronger than the i7 4790K. Generally speaking, it's better to have a stronger CPU than a strong GPU, because you don't upgrade the CPU as often as you can do the GPU. There's nothing wrong with wanting to use the GTX 770 with this new PC. When the times comes, you can just slot in a new graphics card, it'll be easier than replacing the CPU.
