SAMS, people from USA can explain in detail, but for short, was a North American service specialized in making own drawing schematics (generally clearer than from some brands), and, amongst other things, making a local replacement/equivalent list.

In other words. I have it's schematics and parts list.

Any chance you could send them over?

Also man, taking apart this thing is a nightmare, there's so many wires everywhere. You guys make this stuff sound easy!

Am I cooked? I think I broke what looks to be a resistor. It's hard for me to tell because I've not worked on hardware this old. Will I need to replace this piece or will it still work without the outside blue part?

This is a coil***. It seems to have damage only on it's externals. Is easy to test if it is ok. You can measure continuity, since it will have some low ohm value.
***is good to check to be sure in the schema, but seems to be one coil and not a thermistor etc.

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
