Is this level of buzz normal for the tv (i heard all plasmas have a buzz), or is mine a lemon?

Plasma buzzing is normal, all 4 plasmas I've owned do so, but you should only be hearing it, if at all, from within 3-4 ft. If you're hearing it from 10+ ft away then you should definitely get it exchanged. The buzzing is typically related to the power draw which is highest on a bright/white screen. It also seems to vary from set to set so an exchange might be the ticket.
Having said that, at least from my own experience, the 2012 Pannys appear worse in this regard than previous years. My 60GT50 buzzes so bad on white/bright scenes than I can hear it from 15 ft away. I exchanged it and sadly my replacement 60GT50 was even worse, if you can believe it.
My second GT50 is going back next week but this time not for an exchange as I don't have the time to keep exchanging in the hopes that I'll luck out. I'm going to wait it out for a few months to see what Sony and Sharp bring out on the high-end (Sharp 945 series and Sony's next XBR) before trying my luck again. I'm a plasma guy through and through but I just can't deal with the buzzing. It's a shame that Panasonic hasn't been able to get a handle on this issue, at least insulate it enough so it doesn't sound like a fridge compressor.
