There are actually 2 questions. Please split them so it's easier for you to properly grade the experts.

1) Use Screen.height and Screen.Width
In order to get the screen's color depth, use this code:

function GetColorsCount : integer;
var
  h : hDC;
begin
  Result := 0;
  try
    h := GetDC( 0 );
    Result :=1 shl (GetDeviceCaps(h, PLANES) *
        GetDeviceCaps(h, BITSPIXEL));
  finally
    ReleaseDC( 0, h );
  end;
end;

2) You don't generally use TDrawGrid for database access. Use TDBGrid for that. It's available in the "Data controls" tab of the component palette.
