It depends on the type of stain you are using, usually the label contains the correct information, oil based stain generally takes 24 hours, water based takes less time, alcohol based takes even less time. If there is no label, it could be old stain and it might not mix well with your finish. your best bet would be to discard and buy new stain to match with your finish. (water based stain with water based finish, and, oil based stain with oil based finish)
I've never tried that as it's not generally done. Staining is usually done before sealing.You'll have to remove the Thompson's before you stain unless it has been long enough that the Thompson's is no longer effective. To test to see if the surface will take stain, spray some water on it. If it beads up, it will not accept a stain.
Depending on the stain technique it can take anywhere from 2 to 24-hours for the stain to dry. For cabinets, you should wait the entire 24-hours to make sure the stain is not still tacky and to prevent smudges on the finish.

Mount the root tip onto a slide with a drop of water and cover with a coverslip for observation under a microscope.
