Almost any motor/lipo/prop configuration that doesn't overheat the motors will lift a quad. The question is, will you achieve hover at 50% throttle, and will your all-up-weight produce unacceptable flight duration. The motor kv, lipo and props you specd. would work well on an X-quad from 450 to 650 (mm, measured motor shaft to motor shaft on opposite motors). 3ah is a good size battery to start with. Since weight is the enemy of duration, heavier lipos don't increase flight time nearly as much as you would expect.
You might consider just buying a "flamewheel" knock-off at 450mm like this:

I know you can make one, but dude, for less than $20? Why bother? And if you want to get fancy later, you can move all the parts. That frame comes with a distribution deck, so you'd solder on connectors or solder the ESCs.
The Plush ESCs are not terminated, but this HobbyKing PDB has 3.5mm bullet sockets.

And the motors you selected use "grub nuts" which are notoriously troublesome. Better to use a prop adapter so that the load is on the outrunner casing/top and not the shaft. Take a look at these 3S-rated motors:

They will produce 4 x 1040g max with 11x4.7 props! There is no way your all-up-weight should be above 1600g, so you're WAY below half throttle at hover, and that translates into
flight duration.
You're going to need a battery charger, and some servo leads too, since the KK2 doesn't come with any. If you place an order from Intl. warehouse, look at the "super clean" servo extensions. It's a ribbon that only sends power and ground between receiver and controller once. Get at least 2 full sets of props, maybe 3.
Depending on what power distribution board you get, you need to fit or match a battery connector to it, so everything works as you expect when all the parts are assembled. It's a good idea to sketch out your quad and know how you will connect everything, to ensure you get all the parts you need in one go!
