The throwout bearing is the part the fork is holding on to and the collar is that sleeve bolted to the transmission that the throwout bearing is sliding on. Besides the oil leak everything looks pretty good and your pressure plate, clutch disc and flywheel have no oil on them so that is good! Does the oily stuff smell like gear lube? The part of the throwout bearing you can see won't spin unless the bearing is seized up in any position. The bearing part of it you cant see here pushes the pressure plate arms to disengage the clutch when you push the pedal.

That spring looks like a clutch return spring. Your clutch pedal should return clear up including a little pedal free play. If there is no free play the pedal is riding lightly on the throwout bearing causing it to spin all the time, and it should only spin when the pedal starts getting pressed past the freeplay. Usually the spring attaches to the fork outside the bell housing and then will hook to the frame somewhere.

Hopefully one of the V-6 gurus will post a pic of the clutch return spring position for you. I can only show you one on an I-6.
