I wouldn't go flagship because it is a little bit harder to turn then most boards. Since you're looking to bomb groomers you probably want a mostly camber board so lib tech and never summers wouldn't be ideal unless you've ridden them before and truly love them.
If I were you I'd look at boards like the Jones Aviator, Burton Flight Attendant, Slash Straight, or a K2 Peace keeper.
Bindings I would get a really responsive binding like a Burton Diode or NOW IPO's
Goggles are pretty much personal preference, I wear smith I/O.
