Art, you will be wanting more lenses as time goes on.  I suggest you wait to be comfortably a friend with your camera before spending too much on new glass.  I have at least one lens I almost never use because it seemed so needed but in reality has been used very, very little.

Do consider a true macro.  Sigma and other non-Nikon brands offer lenses which do wonderful work so when looking, consider brands other than Nikon only.  Certainly Nikon glass is good but some other brands are also quite good.   The macro can also be a decent prime lens.

I have a friend who never got into trying to go beyond camera settings such as portrait, landscape, etc.  I don't know what your camera offers but try to go with either aperture or shutter priority and get a feel for having more control of the exposure.  I use aperture priority most of the time and use manual more than I thought I would for true control.   Whaleman made a great suggestion of using the EV button, the  + and - to change the exposure. This is a great asset to learn to use.

You will have fun...I know it. You may also get frustrated a bit at first.  Soon enough you and the camera will be quite close friends.   Hurrah and best wishes to you.       Tom.
