I have heard it said, "please keep me updated on this"; "I need a quotation on this"; "We

tinanam0102Would you kindly help me with "...on this" and "...in this"? Before that I thought "on this" was like a common usage?

"on this" is in common usage in all the examples you give (except that I'm not familiar with the expression "get a rush on this"). I'm not suggesting that "Please keep me informed on this" is wrong, or is not used by native
