It's really easy man.. What they are talking about is the Throw out fork wrist pin.. After you take off TMIC, Starter, and Clutch cylinder there is a hex head cap on the upper driver-side bell housing. What you have to do is remove this cap with an Allen wrench then you do as you said, thread a 10mm bolt into the throw out bearing wrist pin so you can use the bolt as a handle to pull it out.. This will disconnect the throw out fork from the trans so you can separate the trans from the motor.. You have to do this because the throw out bearing is connected to the clutch and the fork is connected to the bearing so something has to be disconnected...
EDIT.. Made some pictures..
Here is the location, under the starter..

Granted this is disassembled with not fork or shaft, but you should be able to figure it out now..
Here is an existing "How To" of sorts that I already posted..
Installing new clutch this weekend. Any pointers?
