The one in the upper left is a magjack (RJ45 for ethernet with integrated magnetics). As for SMT, more and more parts are only available in that form. As many who have built Aethers have found out, it's not too bad. The TQFP100 or 144 at the right is a little challenging getting lined up, but doable, even with an iron.
I'm a bit confused by the clump of caps in the lower right...
