The Tamron 17-50mm f/2.8 SP XR Di II LD has a good reputation for being a sharp, affordable fast- and constant- aperture lens, and for being better than its Sigma counterparts. It's DX only, though, but I'm sure that isn't a consideration, since everyone seems to be suggesting DX lenses (such as the 35mm 1.8).
As for wide-angle, I'm surprised no has has suggested the Sigma AF 10-20mm f/4-5.6 EX HSM DC. It's affordable and has a great reputation (more so than its newer iteration with a constant f/3.5 aperture, and much more so than the Tamron 10-24mm). There's also the possibility of the new Nikkor AF-S DX 10-24mm f/3.5-4.5G ED, but for an extra $300 or so more than the third-party alternatives, it's definitely not the cheap option (Nikkors usually aren't).
Also,
What to buy depends on the subject matter. You don't say what that is. When people ask these kinds of questions here and don't provide a lot of details they get answers like "buy what I have, I like it". So watch out for those kinds of answers.
I agree. It seems like half of the posts in the MacRumors photography forums are along the lines of, "I just bought a new camera last week and have decided that the kit lens is worthless what should I buy now anybody?" However, when you look at the original post, you can see that he's very specific about what he wants to buy:
(1) "I am looking to buy a few different lenses."
He's looking to buy 2 or more lenses.
(2) "I would like a wide angle lens[...]"
He wants a wide angle lens.
(3) "[...]and a better general purpose lens than the kit lens."
He also wants to upgrade his kit lens (probably the 18-55mm VR).
(4) "I would also like a lens with a little more focal length."
He also wants a telephoto lens. Or maybe a superzoom. Or maybe just a slightly larger zoom range.
(5) "I have also been looking at a nikon 35 mm dx lens f/1.8 for around $200. I think this would be a good lens for nightshots."
He wants to buy a large aperture lens for night shooting instead of a tripod, which he should be buying for night shooting.
(6) "I don't wanna cheap out on my lenses but I am also far from a professional so I don't need the best."
He wants consumer-grade (and let's say, sub-$700) lenses.
In summary, he wants to buy a wide angle (zoom? prime? fisheye?) lens, a "better" midrange zoom (in terms of... aperture? sharpness? zoom ratio? build?) lens, a lens with "more focal length" (???), and the 35mm f/1.8 for night shooting (at ISO 3200? at 1/5 s shutter speed? with or without supplemental lighting?), all at a not cheap but not expensive cost.
See? A simpler question could not have been asked.
(Also, I haven't mentioned a single lens that I personally own.)
