Nikon makes quite a few macro lenses in different focal lengths from 40mm to 60mm to 85mm to 105mm and 200mm. They are all autofocus lenses and will work just fine on your D7000. All of them will allow you to get to 1:1 magnification while your 55mm will only get to 1:2 without an extension tube. The Tamron 90mm macro is also a very good lens and highly thought of by many of the members here. My personal preference is the 105mm macro lens which gives you a comfortable working distance. However for most tight closeups you'll probably be using the lens in manual focus mode anyway. I prefer my manual focus AIS 105mm f4 macro lens which goes to 1:2 and 1:1 with the PN11 extension tube which has a built in tripod mount. For taking macro photos in the field I carry the Nikon AF 105mm f2.8D. I might be upgrading to the AFS 105mm f2.8G VR lens in the future.
For landscape type photos I prefer wide angle lenses between 16mm and 35mm. My favorite is the AFS 24mm f1.4 lens but it's pretty expensive and I wouldn't recommend getting it until you know what your favorite focal length is. I would recommend getting the little AFS 18-55mm VR lens and start shooting with it. It's quite inexpensive but a very good performer. You can always upgrade later. It covers a nice range for my landscape photos.
