I would still buy a better camera. It doesn’t matter about NTSC/PAL, most goggles do both. You can just switch between them to see which works best.
The motors don’t matter on direction, many modern ones come with only CW threads and nylock nuts, it’s the thread direction that’s sided on cheaper ones. You can run them in either direction. If your motors are listed as Cw and CCW then you need two of each. You set the direction up before putting any props on, like this.

Props are sold in sets, 2 CW and 2CCW, you always need both as they match the above diagram of rotation.
Buy the 10 sets of props for your first flights, you are going to break lots. I run Dal Cyclone 5040 tri blades or Gemfan Flash 5152’s. You are not going to notice small changes in props for at least 3 months of flying, so don’t worry about that. Just make sure you have enough of the same make to cover breaking a few every couple of flights.
My advice is to still buy better gear in smaller batches. Build over a couple of months and end up with less compromises in your finished quad. My last build hit about $180 ish, which is cheap compared to some pre made.
