Yes. The best thing to do is upload as many pixels as you can. Ignore DPI. Upload at your camera's native size (8mpx), and save at photoshop 10 (which is considered to be Lab Quality). You can use 11 if you feel it's necessary. I suggest that you do not crop on your end. Allow breathing room as you shoot, so that customers can order 5x7, 8x10, 11x14, 16x20 etc. Our lab will upres as needed.

300 ppi is same as 300 dpi. but as andy says keep all your pixels in the image and you can't go wrong. setting the pixels at 300 ppi or dpi is unnecessary really. your software, or the printer software when you're using a printing service, will automatically scale the image to paper size.

the magic figure 300 dpi comes from the printing industry -- as in traditional 4 colour mechanical printing presses that make many copies fast for books and magazines. traditionally you make your images a set size and pixel count to help get the stuff -- and there might be an awful lotta pictures on an huge imposition of 16 pages of a magazine, for example, -- through an imagesetter or plate maker faster.

for printing a single photograph don't fuss. just keep all your original pixels and don't worry about the dpi. ;-)

OK, now to stir the pot ppi, and dpi have nothing in common. They are entirely different.
