The Maverick front hub will prevent you from building a truly light wheel. If your 819 wheel is built with 14/15 butted spokes and alloy nipples it is pretty light (that's what I have in front).
Your weight rules out 14/16 butted spokes so the only way I think you could lose significant weight is by switching to a NoTubes 355 rim. It'll drop about 95 grams but is a little flexier. They also make a re-enforced 355 called the Arch that splits the weight and flex differences.
As for the rear: American Classic hub, 32 14/15 spokes, alloy nips, 355 rim, 790 grams.
I weigh 30 lbs less than you but ride a lot harder and my wheels are holding up fine.
