I have a new TC-P50GT30 and mainly want to use Viera Connect and play music from iTunes on my iMac. I could just get an Apple TV, but it seems that people like Viera Connect better (maybe I'm wrong?). I'm networking with an Airport Extreme.

What I'm trying to figure out:
o Will just a USB wireless adapter connected to the tv get me V.Connect and my iTunes music? or
o Do I need the adapter AND an Airport Express?
o Would you recommend just the Apple TV instead of all this? Maybe Roku? (Seems to not work with iTunes though)

Any insight, warnings, experienced opinions would be greatly appreciated. Thanks!
