No, I'm not sure about the kit numbers. You probably could figure that out relatively easily by thumbing through the kit images that were loaded directly on to your PS3.
I have not played with the import function yet (I've barely played the game thus far b/c of busyness elsewhere). The guy I worked with on last year's file (Bolivianfire) imported and has been working on the game; he's probably going to send me what he's been working on to look over in coming days. So I should have a better handle on the import functionality and what's up with the potential of an MLS OF later on in the week.
