What are the best lenses for me?

I have the Nikon D7000 and have these nikkor lenses:
35mm f1.8
18-105
70-300

I'm looking for an everyday lens. When i go on vacation i want this lens to be the only lens i have to take. I'm looking for a lens with a focal length somewhat similar to the 16-85.

The second lens i'm looking for is a wide angle zoom lens. I take lots of landscape and sunset photos.

My budget is pretty tight, around 800$

You have enough for "everyday" photography, the 18-105 mm

What you may want is a nice 10-24 mm wide angle lens for shooting landscapes/sunsets and other subjects that require a wide angle lens

The 18-105mm already covers that function. The 16-85 barely does anything except for a tiny 2mm gain in the wide end. It actually does make a difference, but not worth the price.

You should consider the Nikkor 18-200mm lens instead. It's a bit over $800, but you should be able to find one used under that price.

If you can ignore the 2mm difference between 16mm and 18mm, the 18-105mm should work for you. 18mm is already wide enough for most landscape applications and the rest of the focal range up to 85mm is well within 105mm.
