From the list of things you plan on ordering it looks exactly like the content of the FX kit. If you're considering buying armor piece by piece, you will end up spending nearly double what a hit costs, not to mention you may get parts from different kits and wind up being two difference shades of white.
The Master Replicas blaster for trooping is almost useless. It weighs around 20 lbs. (or atleast feels that way). You will tire of holding it and holstering it would be next to impossible. Also, with limited visibility, you'll wind up either knocking a kid out or gut-checking someone with that beast. It's great for display purposes, but that's about it.
The CABoots are good boots. Mine made it through a 5.6 mile parade with no blisters, cuts, or rubbing with a pair of cheap $2 insoles.
As for the "body glove," you have many options. Many people use a dive skin, which I have no experience with, I personally use Under Armour compression heat gear. You can find various outlets for them online. While you can get the top at most sporting goods stores, the leggings are a bit harder to come by.
