Hi Wade,
For a Newtonian Reflector all you need is the TuBlug and 635nm laser.
I believe the holographic adapter is designed for other scope designs.
Wade, I think the 1 1/4" version would be far more suitable for your scope for visual use. The best short focal length, high mag eyepieces tend to be 1 1/4" so it is logical that you would want to collimate your scope with a collimating system that uses the same 1 1/4" adapter on your focuser that your high mag eyepieces will use.
Low power wide field eye pieces are far less sensitive to collimation where as any error in collimation will be exacerbated when using short focal length high mag eyepieces.
Regards
Trevor
