I'd look for a used stick. I got a X52 for $40, old but barely used. Did the magnet mod for linearity, also CA glued where the shaft enters the handle and now it's more precise than The pro and has no play at all.
I didn't like the soft spring till I removed the extra play which is there because the metal shaft only goes about 1 inch into the plastic handle and is held in place by a 2mm pin. Hence the superglue.
I's also recommend the EDTracker you can purchase prebuilt and flashed for 25 pounds. Previously I had a PS3eye and a home made ir clip. ED is much more smoother and precise, even with the camera running at 120+ fps. It also leaves your desk less cluttered because there is no need for a camera or antenna like IR clip. Just a little box smaller than a matchbox.
Monitors, it's up to you really. I'd probably put that last on my list since I have a 32inch and barely have the gpu to run the game effectively on it.
