The original poster is asking "how do nashville numbers pertain to the drums".
These things you're talking about, like rhythm and tempo, are all things APART from nashville numbers, that may also be present on a lead sheet. Things like "rhythms written above the measure" and "slashes to show beats" are nothing to do with nashville numbers. They are conveyed by other things on the lead sheet.
The numbers alone are not much use at all.
