Choosing my first Nikon DSLR

I'm a college graphic design student looking to purchase my first DSLR, but have no idea where to begin. I have some experience with SLR cameras, and I'm looking for one with great image quality and ISO, but not too expensive. I've been recommended the D700 but it seems a bit out of my price range (I'll be using student loans). Considering possibly a D700, D5000, or D3000? Any suggestions?
PS- I have already decided on Nikon with the guidance of professors and peers, so please don't try to sell me any Canons.

Added (1). I was considering the D7000 not D700.

Nikon D100 - What are the best settings for night youth football game action shots?

My Lens is: AF-S NIKKOR 70-200mm 1:2.8GII ED.

Currently, my pictures are either out-of-focus, too dark, or too light.

When I use a high ISO in shutter priority mode, the pictures are too dark. When I lower the shutter speed, the pictures are too blurry.

Opinions on this photo?

Nikon: Battery Recharging?

So I have an issue - i've heard this before but I want to know if something has changed or if this is a myth?
I constantly find myself with half a battery after a regular photoshoot, I use my battery pack on my D300s. When I want to go to my next shoot, I'm paranoid cause I don't know if I can recharge it to full again or if I need to wait till it's dead. Obviously, I do not want to go into a shoot with half life.

I know my other option is to go buy 2 more battieries for it, so I always have a set charged…

I always go and find something to make the batteries die, but it's kinda of tiresome. Thoughts on this?
WOULD Really LIKE TO KNOW IF IT DOES HURT THE BATTERIES?

Would this be a good 'starters' studio kit?

I'm just now getting interested into strobes, and studio lighting. I have nothing as of now, lighting wise. Would this be a wise kit to start with?

Backpack for DSLR, digital camcorder, and pocket camera?

I'm looking for a relatively weatherproof backpack suitable for carrying a Nikon D700, 17-35mm lens, 28-300mm lens, and 80-200mm lens; a Canon Vixia; and a Canon Powershot SD960 along with basic accessories such as battery chargers. Ideally, the bag shouldn't scream, "Hey, there's a camera (or two or three) in here!" Ideas?
