For my coverart, the site says "If using an image, its resolution should be set to 300dpi". My dpi is set to 600. Is that okay (or better) or does it have to be exactly 300? I would assume more than 300 would mean a clearer image resolution, yes?

Not really - perhaps of the printing process.
One would near a magnifier to notice any difference.
One factor of course would be the content of the image.
300dpi produces the best results with optimum file sizes.

Todays digital cameras all have different pixel depths but the result is the creation of a whole new range of "standard" print sizes that the world of paper manufacture and printer software are simply not prepared for. Ken is absolutely correct that 300dpi at full size is simply perfect. However the new pixel depth is trying to revise this as we speak. An image shot at hi-res and scaled down to size will normally leave you with a pixel depth of 600 or more. The truth is, the information embedded in that resolution does make a difference between the subtle differences in difficult images. Reducing the 600 to 300 in not technically critical, but it is noticeable. On the other hand. I would never ask you to bump up the resolution of a lower res image. It is a huge mistake to think you can create image information.

Thankfully, personal PCs etc have improved no end in recent years, but before this, the limitation DPI wise was often nothing to do with image quaility, it was getting the image through at more than 300; only now can I do this, before, my PC packed up and went on holiday sticking two fingers up as it went. But one other thing to do think about, it may be relevant at some point, 300 is also the magical figure for the universal comparison with standard dimensions, ie, 300 DPI equals 1 inch. I add this as working in a higher DPI may throw you out if you try to base given dimensions such as here on Lulu, on the higher DPI you may use for resolution.
