For just the rear swap, youll need integra (or Si or EX w/ abs) trailing arms with hub assembly (w/ rotors, calipers, pads), brake lines, e-brake cables. These parts will run you $200-300, generally.
To get better brake feel and control in addition to ditching the drums, you'll want to swap out the master cyl also. This part is usually around $50, and depending what kind you get, you may need to change the booster too.
I replaced the front brakes with teg ones too (larger diameter than my dinky vx brakes).
All together, I got raped by shady traders and bad parts. The whole shebang (including aftermarket rotors, pads, lines), cost me more than I care to calculate. Theoretically, you can get all that crap (OEM parts) for about $500.
The swap itself isn't that hard as long as your suspension bolts aren't stuck like mine were. One afternoon.
:edit: also keep in mind, since you have a coupe, that the e-brake cables must come from a 2-door integra, a coupe EX w/ discs, or an Si.
