I imagine its some added strength, my horns must have been missing the screws for several years so maybe not essential

The C version is some sort of injection moulded plastic, its prob not that strong (altec added extra support on later Cs) im not sure it secures anything but i suspect it adds a bit of strength to where the drivers attach, i think mine were missing when i got them maybe 7 years ago and no sign of a problem. Touch wood.
No. Those screws went into the webbing underneath where the horn turned 90 degrees (see below):
32A were cast metal, not injection-molded plastic, so they probably were not needed.
Looking at my 32c’s, I believe the screws were used during assembly. When glueing the horn into the flange, the two pieces were mounted on a jig for proper alignment and the screws were used to maintain the alignment as the glue setup. I can’t see any other use for them, but I could be wrong.
I ordered some of the versa pak/kimsol last January to try out as damping in my altec 32/802g/Jensen 15” speakers. It arrived a few days ago, well over a year later!
For those of using this stuff; it seems pretty thin, are you doubling it up? Currently using wool felt on the back, one side and top and haven’t experimented much.

That looks like it, I got mine on eBay though, it’s 1/4”
I tell you what, finding various insulations we need for our purposes is a real challenge any more. The difficulty I had in tracking down OC 703 was ridiculous, especially in a town like Boise where construction and development is off the charts.
And cotton? Forget about it. The crap that is used in the upholstery world these days is crap and centered on cheap foam.

...is it crap?
Yes, double crappy crap....is it crap?
I had decent luck with denim insulation from Home Despot. Not sure if it is still available, though.
Same, that’s all I’ll use now. Even thinking of using it for sound treatment panels.
Definitely less itchy than fiberglass.
Fiberglass??? Yuk!
Lots of better choices.
I use thick wool felt on bottom and back.
I ordered mine directly from India but it looks just like this:
