And no lens does it all, but one step at a time until you figure out what you can't do with your current lenses.
I'd second the suggestion of the 55-300 (great lens for the money.) Then just go and shoot for a while before considering anything further. Also, start saving.
From time to time, think about what kind of photos you're taking, in what kinds of conditions and at what focal lengths. That will help you decide what to get next. Also, practice shooting with manual focus to prepare to take advantage of MF lens bargains .
