The cup seal is the little white (or sometimes black) thing at the forward end of the valve pin. As for the o-rings, generally, there is only one size o-ring on a Spyder, the only difference is the material used for whether the part moves or not, so, yes, all those orings will work in other places. Here's where you, generally, find orings:
1 on Barrel, made of Nitrile/Buna-N
2 on Bolt, made of polyurethane
2 on valve, made of Nitrile/Buna-N
2 on vertical adapter, made of Nitrile/Buna-N
1 on tank, made of polyurethane
1 or 2 on foregrip/regulator made of polyurethane

The vertical adapter is the piece that the reg/expansion chamber screws into. You can remove that by a little screw that goes into the body. To get to the valve, you have to take off the trigger frame, remove the bolt and striker, and take off the vertical adapter. Once you take off the trigger frame, you will see a little brass screw that's screwed into the body. You'll need to remove that screw then push the valve out of the front of the body using something like a long wooden dowel.

Edit: Read this (http://www.ottersccustoms.com/assemble.html) it will help you understand how to dissasemble your gun. Also, read the rest of his website, it is very helpful in learning how to care for your Spyder.
