Eric Stevens...and remember with Photoshop you can set your crop tool to crop to size & resolution as well as crop to aspect ratio. So I can say, crop to 5:4 and then resize the image for printing, or I can use a 10''x8'' @ 360 ppi crop tool.

original file but 'rendered' at 72DPI rather than the final copy which is mostly likely to be 300+ DPI for printing ?
there is no dpi or more accurately ppi until you print. everything is always done to the original image.
Until you print... or display an image on a monitor screen. Same thing, and a different value for DPI/PPI.
not the same thing at all. set the ppi to whatever you want and the image does not change.
however, if you change the ppi the print will be different.
When it comes to printing ppi, dimension in pixels and physical dimensions are interrelated.
If you don't want your printer driver resampling your image you set the ppi to your printer's native resolution. You then chose final image size and it is resampled to produce the required number of pixels to produce the dimensions at the selected ppi. What you must also do is set your printer driver to not resize the image i.e. print at 100% or full size or whatever the terminology may be.
You should do this before you start any significant editing (except for cropping).
