I half agree with e_lm_70 (you've got all of us cheap guys chiming in )
The Afro's are great ESC's...but they aren't a great budget choice. I've had decent luck ordering from banggood...but they use really slow shipping to the US. One of the slowest places I've ordered from in Hong Kong in fact. So if you're not in a hurry those are probably a decent budget choice. But for the same price RTFQ has his version of the HK F20's pre-flashed with SimonK and since you're in FLA as well if he gets them out the door quick they should be on your doorstep in just a day or two. (BTW - you mentioned you have electronics experience...I saw on the thread at RCGroups about his kk2.0 board that he's looking for people who can solder...if you want to make some extra cash on the side might be worth getting in touch with him.) Of course - that's also assuming you're ok with ordering from him given his questionable ethics with cloning and not directly contributing to the original designers even though it's not required.
As for the motors...Those $7 motors should work...but...I'm not a fan of cheap motors anymore The Suppos are more expensive, but you already have 2 and they're a FAR superior motor that will take more abuse and will probably run smoother and last longer. I'm a BIG fan of low budgets but there are times to be stingy and times when paying a bit more REALLY pays off. And after upgrading from the HK 24g motors to the SunnySky Angels I have no problem paying a few bucks more for better motors now
At $11 each I'm overjoyed with my Angels. I've heard a lot of great things about the suppos but at $15 each I just can't swing them for a quad. Even with 2 on hand you're spending almost as much as a new set of 4 Angels.
There's also the RTFQ "house" motors he says are made by Suppo at just $10.50 each...they're a bit lower KV but higher power than the Suppo's you've already got. And being lower KV they can swing a bit bigger of a prop and have the potential of being a bit more efficient: http://witespyquad.gostorego.com/motors/witespy-red-special-motor-1000kv.html They're also a "shaftless" design which I really like for quads as it seems to minimize damage in crashes considerably.
As for props these are the HK props (from the US warehouse) that I've been using and I really like them:

They aren't "great" props. But for the price they're outstanding and I've tried props that cost considerably more and weren't nearly as nice. I don't have a great balancer (just the HK "Finger balancer" which I rig between some strong magnets to make my own magnetic balancer) but with those props about 90% of them are balanced out of the bag on my cheap balancer. Maybe once I pony up for a good balancer I'll find that my balancer has been misleading me and they're a lot further out of balance than I think they are....but they sure seem to run smooth for me and hold up remarkably well. In fact I knock motors off by breaking zip ties far more often than I break props now.
Though I also fly with chunks missing from them so I'm not the greatest authority on "smooth" props
