sewbizgirl you asked "... I know Liquid Wrench is a good cleaner, but remind me if Tri Flow is okay in lieu of oil, and Tri Flow Lubricant in lieu of grease?"
Yes, Tri-Flow is okay for oil, the consensus is that the Tri-Flow Lubricant for grease on gears is okay, just not to be used in the motor grease tubes on Singer motors that have them.
I'm thinking that Liquid Wrench is okay for shiny bits off the machine, but not cleaning the actual machine head.
Yes, you are lucky. Did you get the manual and lots of goodies in the bench and/or drawers?
