The RR version of Victoria 3 has a lower resolution mesh than the full version. Since morphs are tied absolutely to the mesh they are made for that means the morphs in the set won't work for you - you may get changes due to expression morphs in the RR figure, but that's it. Depending on whther this is a custom morph or a dialed up morph you may need just the base V3 (still available free from download.com) or the base plus the morph packs - I'd get the DAZ figure bundle freebie and see if that helps. (Having checked the product page, Caludia has a custom morph for the head so you could use that with just the base, but the body shape uses the body morph pack.)

As for the eyes - check the readme for the list of files installed files. Claudia appears to have several make up options, but only the one set of eyecolours.
