Thule: Evolution 1800, #415 Bars, V2 590 Rack
Thanks to the tips here (thanks whiteexl, davemac, etc) and my friendly neighborhood sportsrack.com-- picked up a few accessories for my Pilot. Take look:

Total cost $756. Only driven home from the shop so far, but first impression is that you start to notice wind noise at 60MPH. Had it up to 80MPH and it wasn't too bad. Definitely knew it was there. You can almost tell the difference from the wind noise on the side of the car and that from the box, and I'd say the box is producing about twice as much noise (as heard inside the cabin). Not bad. I went with the higher profile (18") Evolution over the newer, slimmer (11"- but same volume) North Cape because I wanted to fit taller items in it. Also, the 50" bars looked nice, but would be pushing it for two bikes and the box. I might hack off the bars in the future to maybe 54".
Thule Evolution 1800 ($418.50)
Thule 58" bars ($38.70)
Thule Foot Pack #415 ($101.70)
Thule V2 590 bike rack ($112.50)
Locks ($32.40)
Got the box for a few reasons. First, I do a lot of backpacking in the Sierras and usualy spend the night before at the trailhead to get an early start. Now I can just sleep in the Pilot and put the gear up top. Also, needed a ski and bike rack anyway, so box is only an additional couple hundred bucks. Finally, figured there is comfortable room for 5 adult passengers so for backpacking or skiing will need the extra cargo room.
One question-- how well do these boxes do in the rain/snow? How wet (if at all) will things inside get?
