Just be aware all new Macs use a
thunderbolt port instead of DVI/AVI/HDMI ports. You can still connect to an external device via an adapter but any multi-screen setup that doesn't involve Thunderbolt displays will require jerry-rigging. So while you can connect 1 external screen via an adapter like
this one, a second external screen would need a usb adapter. Which is why I want the thunderbolts (you can daisy-chain 7 or something thunderbolt devices together that connects to your MBP with 1 port.) and they look AMAZING. If you have an
Apple TV Box you can use airplay to mirror the display of you MBP on your TV wirelessly.
I highly recommend you get a few "Mac Guide" magazines or check out websites. I did about 4 months of research before finally buying my MBP. Also keep an eye out the Early-2012 update can't be far off, mine is the late-2011 model.
