First thing I would suggest, find a dealer/retailer and ask if you can get a package deal for buying a kit all together, you can get some good deals that way, I always give discounts when my customers buy large chunks of equipment or packages, so definantly ask, you can save a lot by bundling
I would definantly look at the BT battle vest, I know a lot of people who have the Genx and always ask for a new one for christmas because they generally only last a season of regular usage, bt vests are built tough,
definantly check out a few shops before you pick one, some of the prices on your list are prety high considering your in the US so I know you can do better without much looking, as for the clothing, most new people start out with surplus because its cheep, but the BT paintball specific clothing is definantly worth it if you have the change for it, built specific to paintball it will work better for you and of course (imo) looks a lot better, the BT clothing line is awesome, I have been using BT clothing since it was released and cant say enough good things about it, expecially the nbew ZE line, just fantastic, not cheep (expecially in Canada...) .. but fantastic
for the remote line, I would check pure energy, proconnect3, or guerilla air (same style as Proconnect, personally I dont really like the Ninja remote lines, I find them to feel cheep, and have longer leads which means less coil so they dont stretch as much.. that said some people love em, I guess its a love hate thing, in the end all remotes are basically the same and will do the same job, so its one thing you can look at based on price, just make sure you get a brand that has wide bore adapters, (and not a little hole in the remote adapter for air) most do now adays, but some still dont, its not that the air hole isnt big enough to feed air, its that some marker ASA's have a hole off the the side, so if they arent on top of each other you can get starvation issues.
as for your tank, if you plan on using a remote, id get a big massive tank, personally I run a 110Ci and when its on your back plus made of carbon fibre, you dont even notice the difference except that you never run out of air, you can get a 90CI Ninja tank for $160 at Hustlepaintball, may want to check with them for a bunch of your stuff actually including the proconnect III remote for $40
