Yes, one should look how the EW sits against the pallet stones before taking decision to where it must go. But pallet stones itself are wide enough (I mean in height) so small change in EW position in height will usually not change the correct interaction.

Indeed it's something that will have to be investigated. If required, both settings may have to be adjusted but if it is a minor shift (a few hundred of a millimeter) it should be OK. Ideally, the escape wheel teeth should be centred on the impulse surfaces of the pallets.

Sure, but not if both of the depths are adjusted accordingly to keep the stones and escape teeth centered. Also Important is to keep all of the escapement endshakes to a minimum. 

I would come back for a refresher talk on what to do when your jewel press arrives.
