Here is the card:

Date: What date do I put here? The date manufactured (which is 04/92) or the current date?
Vehicle Serial No.: Nothing on my car says this, might they mean the VIN?
Dealer Code: What do I put here? The car was originally from Subaru of Nashua ( http://www.subaruofnashua.com/ ) but I bought it from the previous owner himself. Or might this be another number on the car?
Engine No.: The car's handbook shows there this can be found on the engine, but there are two stickers where the handbook points. The first shows 505151 and the second shows 3V-TY752VA2AA, which do I use, or do I use both?
