We never had the compact here in the states. Only on the E36 chassis. I converted several to M3 spec with suspension/brakes/driveline.
Looking up part numbers becomes problematic owing to BMW's penchant for issuing a different number for even the slightest of change. Albeit a good place to start.
As to the earlier compact the entire interior was different from any; be it the sedan, cabriolet or coupe.
Perhaps someone here knows more about the inter-changeability of parts for the E46 compact/sedan. I doubt there's more than a dozen or so here?
Insofar as the door cards etc, you might start looking at the ETK in group 41 (body) with two tabs open. One for your car and the other for a coupe, sedan or M3. If things like the door or door skin are the same, there's a fair chance that the cards will fit. Going deeper onto the door cards themselves likely would not bear fruit. You've got to get a couple of layers out.
