No smoke except sometimes on start up.

I can't comment on that specific vacuum reading as my gauge reads in inches..but in that case 20-22 inches of vacuum is typical for a good running stocker.
Compression numbers sound very good for a low compression engine. Low compression is the one cylinder might simply mean it's time for a valve job. But I'd say the engine has plenty of life left in it.
Start-up smoke is likely just exhaust guides and valve seals.
