Oops, forgot to answer this part. It almost depends on how you print and how picky you are about your pixels. This advice is just for when you don't want photoshop to create any pixels at all so that you're only working with the true pixels from the camera.
So say you want to print a 4x6 image of your photo. Bring up that same Image Size window and uncheck the Resample Image box. But instead of changing ppi, you'll just want to change the actual dimensions (inches) to reflect the 4x6 that you're looking to print. You'll notice that the ppi will change to what the resulting ppi would be when it gets crammed down into the appropriate size.
Generally, the more pixels you give your printer (or more appropriately your print driver) to work with, the better it'll print. Your printer will basically take all these pixels and try to figure out how best to lay down the tiny little color dots to try to replicate the image you are sending it.
I have read though that home photo printers do have an "optimum" ppi that allows the printer to produce a superior image. It was from one of my "Shutterbug" magazine issues, but I can't recall which issue.
