The resource forks live in the "AFP_Resource" stream, and the other
file info in the "AFP_AfpInfo" stream.  There's also a "Comments"
stream which used to be used for Finder comments, but I don't think OS
X uses it any more.

For those Windows apps (not all) that understand multiple streams, you
refer to them as "filename:streamname",
e.g. "c:\temp\foo:AFP_Resource".  But that's only useful if you're
looking at it on Windows; if you're viewing it from the Mac over AFP
then just use the Mac native mechanisms.

When doing a search I discovered the "Fork Server Helper" app which
might be useful to you, as it's designed to convert between resource
fork storage formats.
