'Get the D7000 if you can afford it. That will allow you to use some of the excellent AF-D lenses you can get used/refurb.
However, assuming AF-S lenses, "indoor" covers a lot of ground. $1000 is not an optimum price point. Nikon really likes to price their top lenses in the $1500+ range.
The best zoom for DX is the 17-55mm f/2.8 "pro" zoom. New for $1499, used in perfect condition for $1350ish.
However, I would not go that route. There are great lenses that you can get that will take great shots.
The 18-70mm f/3.5-4.5 is a great lens. Coupled with the 35mm f/1.8 for low light and you're set. The 18-70 is $250 Nikon Refurbished, or $199 used in E+ condition. The 35mm prime is $200. For less than half your budget, you're pretty well equiped.
The 18-55 kit lens is very sharp and can be had in VR, Nikon Refurbished for $99. Both the D5100 and the D7000 are outstanding low-light performers and will let you get by with a bit slower lens.
Ultimately, you'll want to acquire some fast primes. Really, these can wait. The inexpensive Nikon lenses are so good you can do a whole lot now, and save for the pro lenses to get when you know exactly what you need for your art.
The 50mm f/1.8 is a neat portrait lens on DX, and will run you about $250.
So, for $750 you can have a sharp 18-70 zoom for a "stay on camera" lens, and two excellent f/1.8 primes for low light (35mm and 50mm).
Add the surprisingly good 55-200mm f/4-5.6 zoom for $130 (Nikon Refurbished) and you are set for some time and still have $100+ to take the wife out for Dinner and a Movie.
BTW, if you get the D7000 you can get some of these in the AF-D save a couple hundred dollars. Plus there are some neat f/2.8 "pro" zooms out there in AF-D for 1/5th what new AF-S VR zooms would cost.
