Commons and uncommons I'm more likely to have for you - most of those cards you listed, I either have and really want or don't have and really want! I mean, everybody wants 4 BoP!
As for advice, the only bit I'd give you is that I reckon drafting is the most fun way to build up your collection and so I would recommend you do that as much as possible! Especially go to (pre)release events, do reasonably well in the sealed and get into the top 8 draft - then rare draft like mad!

There's normally some prize for the top 8 draft that the serious players want, and so they are trying to build the best decks, which means they pass SO MANY RARES! At the Shards prerelease, I got into the top 8 and picked up I think 13 rares. Sure, I lost the first round and got knocked out, but does that really matter?
