I watched Season One of Lost the summer after Season Two aired.

Aside from the stuff you posted, I've read the Dark Phoenix Saga, Phoenix: Endsong and Warsong, most of the recent Uncanny X-Men (which I started to get bored of over the past few issues), the arc in X-Men where Gambit turns into one of Apocalypse's horsemen, House of M, Son of M (I a little bit love Pietro?), most of Messiah CompleX, New Mutants and New X-Men (the one with the kids). Also, Runaways.
