Help Me Identify These Leftover Parts For Clutch/Trans Work Please

[S2G-Unit]

I'm about to have these things changed/installed on my 1994 MT:
-OEM Clutch
-Fidanza Lightweight flywheel
-Clutch master & slave cylinders
-Transmission seals & bearings, brass synchros, diff bearings & possibly replace worn gears

I've done a lot of reading over the past year but now I have a few parts that I need to identify:
-12209-pr3-000
-91307-PR8-005 I have 3 in total but it seems like I only need one of these?
-91352-SD4-000 Don't think I'll need this because I'm having this installed "ScienceofSpeed Clutch Slave Hose Kit - NSX, 1991-05"
-90705-PG2-000 For some reason I have only 2 of these? Seems like I would actually need 4?
-90602-PR8-000 I have 2 right now. Seems like I'll only need 1?
-90471-580-000 I have 2 right now. Seems like I'll only need 1?
-91216-PR8-005 I have 2 right now. Seems like I'll only need 1?
