So on the flashes, (also known as speed lights). Your 200 has a program in the menu known as "Remote Commander". The camera can control most of Nikon's speed lights without a remote connected to the hotshoe. I have these.
Honestly, I have 4 of the speed lights now. For some reason they started to go up in price a few years back so I snatched a couple up on fleabay. The larger speed lights should be able to fit your stuff.
