I really like Twilight Princess. I played it when it first came out on the Wii and I thought the motion controls worked fairly well, though I'm sure it works equally well with traditional controls. I think they really nailed the atmosphere and Midna is such an interesting character. And like Cary said, Zelda is awesome in this one.
It's my all-time favorite game, so I'm a little biased, but yes, you NEED to play it.
Wait wait wait, you've never played Metroid Prime?! Stop whatever you're doing and go play it right now. No arguments, mister, just GO! 
Yeah, he does a lot of good stuff!
I actually own a physical copy of the Motroid Prime soundtrack. So good!
I was going to say that that was cool but by the end of your comment I just felt really awkward, so...
Well, pretty much the stuff I mentioned. Year One and The Dark Knight Returns (both by Frank Miller) are fantastic bookends to Batman's career. The stuff by Jeph Loeb is very good. The Killing Joke is another. It's pretty easy to find out which ones are good 
If there is older famous stuff you still want to read, definitely try the library since they are most likely to have that. I snatched up a copy of Watchmen on my first trip there (still need to read it!). As for obscure stuff, there probably is no better way than getting it as it comes out. As long as you enjoy reading it
Won't know till you try! You might be pleasantly surprised and who knows, maybe they have the...Dune prequels now. I tried listening to a comics podcast once but was pretty bored since I don't follow that industry at all and don't have too much desire to. With decades' worth of great older comics out there, I don't feel a need to keep up with new stuff. A show about comic history, though, would be more interesting, I think.
