What is the best way to achieve bokeh with a nikon d90 w/ AF-S DX NIKKOR 18-105mm f3.5-5.6 G ED VR? Thanks for the help! This is my first dslr, so i need a hand.

"Bokeh" is a term that refers to the quality of the out of focus rendition given by different lenses. The term came to the USA through noted photography and darkroom techniques write Mike Johnston, who has a blog called The Online Photographer; Johnston introduced the term to the USA in the 1990's.
A lot of people confuse backgrounds that are out of focus with "bokeh", but that is not what bokeh really is. I think what you are trying to achieve is simply a well-defocused background,with a sharply-rendered foreground subject. If that is the case, what you can do is to use longer focal lengths and wider lens apertures, and place your main subject relatively close to the camera, and make sure that the background is quite far behind the subject; this will give you the most-defocused background you can get with a DX sensor and an 18-135mm kit lens.
A wider-aperture lens would help in getting the background to render more out of focus; at longer distances, like say 45 feet from the camera, with a DX sensor and a 135mm setting at f/5.6, the background will not be what is called "blown out" but would be more what many would describe as "softly out of focus".
There's a young photography enthusiast on here who uses a D90 and the new 50mm f/1.4 AF-S G prime lens....that lens renders backgrounds pretty well out of focus because of the focal length and the really wide aperture, and the relatively close range which it can be used to frame subjects on a DX body.
In terms of lenses that have really good bokeh, Nikon has a few really nice lenses. 85/1.4, 105/2 DC, 135/2 DC, 200f/2 VR, 70-200 VR, and to an extent, the 300/4 AF-S.
The quality of the Bokeh a lens produces is almost entirely governed by the shape and number of aperture blades.
A lens having 5 blades will not produce boken as smooth as a lens with 9 aperture blades. The other blade property that counts is the shape of the blade edges, sharp or rounded.

You don't need a wide open aperature to produce Bokeh.True, the quality is governed by these factors. However without a wide open aperture, the DOF will simply be too large to render any bokeh, whether it be good or bad.

I can still produce Bokeh with a 500 mm lens at f/8. My DOF will be exactly the same (0.07 ft front and back) with my subject at 20 feet, as a subject at 4 feet using a 50mm @ f/1.8. Both will also have the same Circle of Confusion of .02 mm.
The deciding factor is the distance from the subject to the background.
I was bored this past winter and did this comparison of bokeh at 200mm & 300mm for S&Gs.I can still produce Bokeh with a 500 mm lens at f/8.
The same nose I shot with the 50mm at 4 feet. Of course.That's convenient if you want a portrait of someone's nose!

Think I'm going to make a whole series out of noses too. :thumbup:
