You can call the Delete user procedure by using
membership.DeleteUser("UserName")
The Membership Provider will feed it the parameters.
DeActivate is simple just create a procedure to set Is Approved to 0. You can also use a gridview and sqldatasource to list your UserNames and IsApproved columns, then enable Edit mode on the grid view and change the approval that way.
Hope this helps.
