For your price range, most any prime lenses (lenses with fixed focal length, ie 35mm, 50mm, 85mm) with a F-stop (aperture) of 1.4 are gonna be way out of your range. Nikon does have a great little $200 lens. 35mm F1.8. But if you need something with more 'reach', dont be afraid of lenses from Tamron, Sigma or Tokina. They have F2.8 lenses close to the size of you current 18-55.
But what you are looking to do is mainly created by the larger F-stop (numbers are backwards. Lower number = larger aperture, higher number is smaller aperture). A larger aperture focuses in a smaller 'plane' (---->||<----) and creates the out of focus 'bokkah' you see in portraits. Smaller aperture has a large plane of focus (->|-----|<-) and everythign in the photo will probably be in focus.
Theres a nikon forum which has alot of info that will help you alot. www.nikoncafe.com.
