Hi Dustin,
Qu #1 - not-sure, but I used to often shift my 122 without using the clutch, ever tried that? If it goes in easy, you know it is the clutch, but it does require some practise (fun though

). I don't have a good picture of the inner-workings of a tranny, but someone here can probably help you.
Jack-points: probably rear diff and front cross-member. Then you can put jack-stands under the old jack-points, or on the axle in the back and frame on the front. Mine is currently up 3 feet on the jack-points.
When are you going to stop-by? I've just sandblasted the whole bottom of my car - so it is all covered in plastic and masked-up - so not this week, but I'd love to see your wheels.
James
