Both are reasons you should always bias the mount to be slightly
'east heavy'. Doing so insures that the play and lash are taken up.

I'm not a Losmandy mount expert, but I've built and repaired a number of worm gear driven equatorial mounts over the years. A minimal amount of lash between the worm and the worm wheel is acceptable. Depending on the mount, about 1/8th of a worm rotation is the most there should be. However, I respectfully disagree with the statement regarding lateral movement of the worm/worm shaft between the bearing blocks. For a mount to track properly, there should be zero lateral movement of the worm shaft between the bearing blocks.
