I have also applied for and received approval for TRUSTe's Privacy Seal
I would imagine that your site will be listed and linked to from their list of participating sites. The list of participants is very large, so I would guess that any PR passed (from this page) may be minimal. Remember, PR is passed from the page where you're link is posted.
Check the backlinks for some of the other participants and you'll get an idea. I can recall seeing a few PR4's on this list the last time I checked. :)
