As for the photos...
Try to take the photo from a bit farther away then crop the surrondings so only the plane is the shot. This way you will reduce the overall size of the photo and then resize it to 800 x 600.
Don't use compression settings for JPG, most likely this is the problem.

Piggybacking on this excellent advice, I would also ask what ISO setting your camera is on. If you are shooting in a low light condition, the camera may automatically choose a high ISO setting without you doing a thing.

Try this: take the model outside on a day with lots of light and shoot the same image. Process the image exactly as you did for this forum. If you get less grain, then, you have found your problem.

For indoor shooting, eliminating grain is an easy fix: manually override the ISO setting to shoot at ISO 100 or 200. Mount the camera on a tripod to eliminate camera shake. Shoot away!
