Can I use this with small tanks they use for cars to add them to refrigerators?

Yes, it works if the refrigerator has the R134A R12 R22 or R502 refrigerants.

Can't attach hose to my car, the low and high pressure valve has a inner tread not an outer threaded nipple?

Not sure of your question but I believe you're referring to the shriader valve. You can see visible threads internally. Most modern cars use R-134 that use the quick disconnect. If your vehicle is from this decade you would need to use the quick disconnects that thread onto the hoses.

Will this set hook to a large refrigerant tank

Yes, it can hook to a large refrigerant tank.

Will this set have everything needed to recharge old r-12 system?

Yes, but you will need a high side adapter/fitting and I would strongly recommend that you get thumbscrew core depressors for standard R-12 and other (1/4" & 3/16" flare) access ports.
