Megapixels do matter. Don’t let Mr. Rockwell fool you.

Pixels do matter when you make enlargements or prints from cropped images.

If you can afford it go with the D90. (Try to avoid the D40 or D60 if you can.)

"only" 6 mp tells me you have been listening to the marketing people.

I have tens of thousands of image files shot with a D100, 6 mp camera being used as stock photos. The 6 mp sensor on the D40 is a newer version.

It is the size of the sensor and the quality of the lenses that should concern you … the D40 is still a viable camera and will serve you well for many years to come.

If and when you decide to go pro (after a few years of school and experience), the D40 will do everything you need a DSLR to do. When you eventually get ready to spend $5000 on a pro camera body, you will find the technology will have advanced another level again … (from the exquisite D3)

The camera itself.

Unless you intend to really enlarge quite small portions of an image, then 6MP is going to be perfectly adequate for most enlargements.

It is difficult to compare point and shoot cameras with very small sensors (and resultant noise issues) with DX or FX format sensors. These are much larger and generally do not have the same noise problems.

As an aside, if you do find that you are enlarging small portions of an image, then you need to consider whether you need to change position or lens length or both. The subject should ‘fill’ the frame. Digital manipulation offers some fixes for bad technique, but is not a panacea.

I have a D40, and agree with Ken Rockwell; 6 mp is fine. Another feature of the D40 often overlooked is the flash sync shutter speed. On most cameras, the fastest shutter speed you can use with flash is 1/200 or 1/250. With the D40, it’s 1/500 (or higher with some flashes). This makes a big difference for daylight, fill-flash pictures. See: http://www.kenrockwell.com/tech/syncspeed.htm
And if you do want higher res, skip the D80, and go with the D90.
