What Nikon accessories / equipment?

I would like a flash to accompany my d7000. I was thinking the sb 700 what's your opinions on that? Also I wanted another lens I already have a nikkor 35mm f/1.8 and a nikkor 55-300. What additional lens would you recommend getting?

The SB 700 is an excellent flash, but do you need one at this point in your learning phase?

Are you saying that you do NOT have something in the range of 18-55 mm? That is the range where you can shoot landscapes, groups, full body shots and head and shoulder shots. The 35 mm is too short for shooting portraits, so I'm a little surprised that you did not by a 50 mm f/1.8.

Your D7000 is an amazing camera. Before spending a dime on more lenses, learn to use the D7000 so you can intuitively pick the correct lens for the subject you are shooting and don't have to think too much when shooting using the cameras light meter in the manual mode
