At first glance, the price is very good. But, they are not giving you any information on the lenses. Are they D, E, or G lenses? What is the speed? The speed of the lenses effects what ASA you are going to have to shoot at. Higher the ASA (Shutter speed to make it easy), the more grain or noise in the picture. Once you buy a good camera body, your real investment is in the lenses. I am not a fan of these "Package deals" as I know what I want and what I will use. The G lenses are basically crap (plastic optics) and your pictures will show it. They are priced accordingly. They are Nikkor's way of bringing entry level people in who will upgrade within 6-12 months.
One of the first things you will need is a spare battery and you never see those in the package deals. I do a lot of sporting events and use a bessler battery pack for those. The pack will last as long as four batteries and I don't have to switch out but I am carrying a sling over my shoulder the entire time. For general picture taking, vacations, kids, etc, I use the normal camera batteries and carry two. One in the camera and a spare. Nothing worse than losing battery power and not having a backup.
If you are going to invest in quality equipment, do it piece at a time and do it right. One thing that most amatuers don't do is ALWAYS use a flash. You need to invest in a good flash and you cannot beat the Nikon Speedlites. A flash should be used in every environment, period. Unless you are trying to achieve some kind of desired errie effect, a good flash is a must have. Even the models that come with a built in flash, I would upgrade by purchasing a Speedlite.
People talk about buying memory cards. Do not buy used! A memory card is only good for so many writes and then they fail. And they fail without warning. I carry two 2G cards. I use one all of the time and when it fails, I have the back up that has never been used. I am currently on my 3rd card if that tells you anything.
Hope this helps. The real keys to enjoying photography and taking good pictures are 1) A good body (camera), 2) Good lenses, 3) A good flash (not the built in ones), 4) A spare (charged) battery, & 5) A spare (not used until needed) memory card. Oh and least I forget, you still need a steady hand. Both hands on the camera body and elbows tucked in for best results. Nothing worse than "Camera Shake".
