Kittywolf13,
Happy Birthday!
Tri-Flow or sewing machine oil in the oil places, Tri-Flow or Singer grease ( lube ) on the gears, Singer lube in the motor. The owners manual will tell you where to put it. I much prefer the Tri-Flow.
Bobbins are available from several places but my favorite is Sew-Classic {

The little thumb screws go to the presser foot ( it's there ) face plate (looks like yours is missing), and the fabric guide which uses the holes just to the right of the needle plate on the bed.
Nice machine. I'd use oil and a soft cloth to clean it. As for polishing it, I'll defer to Miriam on that one. She's recommended something to me and my pea brain isn't remembering what it is right now.
