Hi Knightrider.
The thing you need to remember is that the laser can only check the final alignment of the primary. So you should use the Cheshire first. In fact many suggest that Cheshire collimation is all you need.
There is a very good guide here

which I think is an excellent intro to the joys of collimation.
I wouldn't be adjusting the focuser tilt unless it is way off, in a scope your size it is unlikely to make much difference.
