how much are my car parts worth?

i totaled my '97 GS-R, and i'm lookin into parting out the car, but i have to know if it's worth it or not to buy back from insurance.
since i pretty much don't know jack, i need help from the experts to tell me how much i can sell my parts for. i have some ideas, but i need your feedback.

-complete engine -$2500 (is this reasonable if i tell the person to take it out themself?)
-transmission w/B&M short shifter - ?? (or should it go with the motor?)
-AEM CAI - $110
-GReddy Evolution Catback - $375 (Dented muffler)
-Tenzo R rear lower tie bar - ??
-H&R Sport springs - ??
-Bilstein shocks (if still okay) - ?? *or should i sell suspension together?
-Stock GS-R front tower strut bar
-Leather seats - i saw someone sellin them in my area for $700. reasonable?
-Gauge cluster - ?? (like the engine, is it reasonable to have the person take it out themself?)
-Hood (i'm pretty sure it's still okay) - ??
-Stock Rear Tail lights - ??
-fake ITR shift knob - $15
-Stock Leather shift knob - ??
-Stock Deck and Speakers - ??

if there's anything else you can think of that i can sell, feel free to add to the list. if it helps at all, i'm located in the CA Bay Area. (San Jose)

thanks in advanced for the help.
