Tore out some flooring in a half bath downstairs. Im steadily scraping off the glue etc to get down to the concrete. Was just wondering how much do I need to get off?..Its patchy looking, not sure if I'm over doing it by getting every dime sized piece of glue off or what.

Generally yes, you do not want voids that will affect the replacement product.
