Amstaff - are you preparing to do your own transmission work? It is possible that some of those pieces can be used to remove the engagement teeth from a gear. Two sizes are needed for the 915 transmission. Basically, you use pieces to lock under the engagement teeth part, and set them on or into what is sort of like a die. You then drive the gear part out (or press it out if you have a press. Installing new teeth involves pretty much the same setup, but the other way around - you drive the gear into the teeth.

If I had them in my hands, I'd go to my stock of spare gears (now much smaller once I decided to throw away my much larger stock of damaged gears) and see if any of these fit. You could do the same by taking them to some friendly nearby Porsche repair shop to see. The owner might even recognize them. They don't look quite like the ones I own, but there are various sorts.

You could also thumb through your Porsche shop manual - it lists all the tools needed, with pictures of special ones.

The notched C shape piece looks to me, too, like one flavor of brake band. I don't know what use can be made of that as a tool.

You can find a great tutorial by Peter Zimmerman (do I have that right) here on Pelican on the transmissions of 911s. That might help you if you don't have shop manuals and the like.
