I think you've basically got a first question you haven't asked. Are you writing a C library that you want to interface with in perl or are you writing an XS library? If the former, you should probably translate them into a broader structure that includes all of the options you're looking for (or pass them as plain parameters into the remainder of the code). If the latter, you should stick with Perl datatypes.
