Concerning your equipment, another option is to go for a fast prime 35 or 50 1.8, they are really bargains. My light travel kit is D90, 35 1.8, 16-85(some times the 10-24) and 70-300. The 35 1.8 sits on the D90 most of the time. I'm still in the process to "learn" how to shoot with a prime, but getting more involved.
