Can't comment on what is "recommended", but I scan 10x8 prints at 300dpi. After cropping and making any minor adjustments to colour and/or contrast, down-res to around 800x600. I then upload the final images to a server as plain old jpegs with about 75% compression. Sometimes I have to clone out a dust spot, but that is as far as I go.
