does this darken the color of the stone? does the stone look different at all after it dries- including sheen?

I saw no change in color at all.

Does this product need to be diluted with any other thing?

No this product is ready to use and does not need to be diluted.

If you are sealing around outside windows, do you need to tape off the windows? Does this harm windows or metal painted trim around windows?

I used it on brick and stone and actually coated a metal mailbox with no issues. I would probably tape off the glass.
