1991 GT Convertible, 128k miles, new rear end / axle in 2000. Sat on blocks in the country for 14 years untouched.

I'm new to car repair/restoration but, after a good bit of work, my son and I got it cranked. (New fuel tank, fuel pump, worked the "crank but no start checklist" and got her going.) Have driven her 2x. Noticed a lot of white smoke coming from fluid on the catalytic converter. (I think. I refer to the "short triangular prism" looking piece just rear of the headers.)

Looked underneath and there is what appears to be old-caked-on-burnt oil everywhere. On the front of what I think is the forward-most part of the transmission (just to the rear of the oil pan), there appear to be 1-3 missing bolts, and the structure sounds very hollow. You can see in the pics where I have cleaned up some of the surfaces, but still get a feel for what a mess it was.

So my questions are:

Is the hole that the red arrow points to normal? Is the amount of fluid leaking from the yellow arrow area normal / acceptable?

Am I missing parts where the blue arrow points? (There appears to be a gasket there, but I can't really tell.) Am I missing a bolt where the green arrow points? (it's threaded but there is not a bolt in it.)

Am I on the right track that this is a transmission leak? Any guidance on next steps to fix this mess would be much appreciated. Thanks!
 
Yellow arrow indicates rear main seal leak.

red arrow is normal

blue arrow. No gasket. That's an inspection cover to get to the torque converter. I believe only two bolts hold this plate on.

Green arrow. Don't think so but not 100% sure. However looks like there hasn't been a bolt there in a while
