I have a shared library (.shlb) that I want to use, but I have no idea how to call the routines in the library from Cocoa. I've searched the list (and found one thread about calling shlb routines, but it didn't have any answers), and searched Apple's site but have come up empty.

There is some same code at Apple, but it's about calling Mach-O routines from Carbon, but I want to go the other way. How do I load a shared library (.shlb) and call Carbon (CFM) routines from a Cocoa > app?

The easiest way would be to wrap your shared library in a bundle and use CFBundle; it will handle the cross-ABI issues for you. If this is not feasible, you can call CFM code from Mach-o code with a small amount of assembly glue--look in the documentation for the cross-fragment calling sequence.
