Don't know about how to accommodate the eye movement in a custom character, unfortunately.  That's one thing I haven't tried in a modelling package.  Or rather, I know how to move the eyes around (that's simple enough) in Wings and the like, just not how I'd then implement that back into Poser.

You can export more than one body part at a time in Poser, however; select them from the dialog box when choosing the export option.

As for the reflection on the eye, you'll find an image map attached to the Cornea or Eye_Surface material (or whatever they are called on V4).  That's the thing you need to delete.  I believe BagginsBill has some much better eye materials, which you'll most likely find in the big Material Room discussion thread at the top of the forum.  Failing that, someone will point you in the right direction.
