The UVs aren't used, no... but Poser's obj import and export functions are problematic, so it's smarter to use the original figure .obj, which of course has UVs. Whether or not you need to peel them off depends on whether the program you use has difficulties with them... I had bad luck early on, but OTOH, I really didn't know what I was doing at the time, and I'd prefer to be safe.
