This varies with different needs. If you have definite ideas about your special needs, then you can skip the kit lens and go for the specific lens you need. But if you are not sure about what you like to shoot or need, then getting the kit lens will give you a good start. You should play around with the kit lens 18-55mm IS for a while, get familiar with the different functions, depth of field, focal length, shutter speed, metering, exposure control and compensation, etc. Then you may figure out what is missing from the kit lens, and go and buy the second/third lens. Perhaps you will need a fast tele (f/2.8 or faster) for night sports actions, macro for the little critters, soft lens for special portraits, superwide angle for landscape, tilt/shift lens for architectural studies, etc.
In general I will suggest to avoid the superzoom lenses. If you like superzoom, then consider the fixed lens superzoom. You decide to pursue D-SLR with interchangeable lenses, so you should take advantage of the changeable lenses. Superzoom lenses always have lower quality and compromises. If you just slab a superzoom lens on a D-SLR, you will not get too much more than a fixed lens ultrazoom camera. Many people will eventually discover that they need a fast lens with wide aperture for a nice bokeh effect or for handheld night photos. Superzoom lenses are all slow lenses, especially at the tele end.
I also strongly suggest you to consider getting an external bounce flash. This will help you a lot in learning how to control your lighting (using fill flash, second curtain flash, adjust flash output, etc). If you are interested in portraits, then also consider getting some studio lightings, reflectors, softboxes and backdrops. Green screen or chroma key is another really fun fantasy portraits that can be done easily at home, and wow your family and friends.
And of course you should have a tripod sturdy enough to hold the camera and lenses. Tripods will let you take some very fun long exposure night shots and keep you photos sharp.
There are also a lot of softwares that can make your postprocessing a snap and save you hours of painful editing.
There is a lot of fun and things to learn in photography, but you often have to spend some extra money to get the right accessories to make it more fun and enjoyable, and to expand your creativity. So don't dump all the money in just the camera body and one superzoom lens. You won't have as much fun.
