1) It looks like both your VHF selector & VHF fine tune knobs are missing.
2) try a VCR on it.
3) IIRC the RF input is a 3.5 mm jack. To hook up you need the right adapter (s)
for the coax. That would be F- fitting to 3.5 MONO.
4) That is a coil. Looks like it had glue on it.
This is not an easy set to deal with. Forget about a re-cap until you
work on some more forgiving sets.
Easy for us ? Most of us are former techs or long time hobbyists.
You do learn a bit after being inside tens of thousands of TV's
