I know that amazon.com has the D50 with both kit lenses for $900 which is a very good price. If you have an address in the US you can ship it to it will also be free shipping. Both the 18-55 and the 55-200 are good lenses. They're not Nikons best, but they do take great pictures. Kelly mentioned getting the Nikon 18-200mm lens, however, it is VERY difficult to find and is expensive ($799 retail and goes for over $1000 on ebay), but it is an excellent piece of glass, especially that it has VR (vibration reduction).
There are other options for lenses. The Nikon 18-70mm lens has longer reach and is a bit better optically, but it retails for $400 (can be had referbished on ebay for about $230). Combine this lens with a 70-300mm (sigma or nikon) and you have a longer total reach, but will pay more for it.
You can go the single lens route with the Sigma 18-125mm. Then later down the road (and this is the beauty of SLR's) you can get other lenses based on your photography habits, like a 10-20mm Sigma or an 80-400mm Nikon or the granddaddy in the Nikon line the 70-200mm f/2.8 VR lens. There are way to many good lenses to choose from.
You really can't go wrong with the 2 official Kit lenses for Nikon. It gets you started at a very good price and like I mentined before you can always get more lenses in the future. Thats really where you want to spend your money.
As for media cards. Buy.com has some great prices on SD cards, especially the Kingston 1GIG card. I have one of them and it works with no problems. Goes for about $30 and there might even be rebates involved to get it lower.
The kit will come with a battery and charger. You will need an adaptor to use it in Europe. I have a 2nd battery that I used while in Disney. Got it at a local
Best Buy store for $40. Its only 1300mAh compared to the 1500mAh that comes with the camera, but it still will give you lots and lots of shots. I haven't had the need for the 2nd battery for use other than while at Disney thus far.
Good luck.
