That's strange. The meter should correct itself (to take the flash into account) as soon as you physically pop the flash up.
Nope. I had the same problem when I was first playing around with the flash (both onboard and SB 800). The Electronic Analog Exposure display only records the light actually entering the lens at that time
(although it includes adjustments made to exposure compensation).
The reason it doesn't take the flash into account is because the camera doesn't know exactly how much light the flash will throw out until the pre-flash fires - which is when the shutter release is pressed. I'm not sure if pre-firing the flash (FV-lock on the D80) would update the meter display. I'll have to test.
P.S. You've got a really nice photostream Welly.
