I suspect the group names for your arms and legs may be wrong. Group names are critical. The obj group names of your arms and legs must be the same as the ones used in the catsuit cr2, right down to the capitalization. Load up the catsuit obj file to check the group names or look at the geomhandler statements in the catsuit cr2. Making your mesh into a posable figure sounds like a lot of work. If you have a separate prop for each body part, just use the group editor to create an appropriately named group for each one. Once you've done that use file->export->obj in poser and in the final dialogue, select the box to preserve the existing groups. Your mesh should then be ready to go.
