Bridging gives the PlayBook access to the net through the BIS (and for those who have it BES) connection and so goes through RIM servers. Tethering gives access directly to the net from your carrier so doesn't go through RIM servers. Tethering may involve extra data charges depending on your carrier and plan, so consult your carrier before trying it.
Sorry, my eyes slipped down to smoothadmin's post, which is where I say VMC.
I have not tried using the native messaging app via the bridge yet, I'll see if I can try that tonight, but since I'm on BIS/BES and with Rogers my results may not have any bearing on yours.
My other Blackberry is a PlayBook.
