ALL HAS BEEN SOLVED. The main issue here was actually the floyd posts - I was under the impression that the bridge was at parallel and therefore the only way to lower the action by the truss rod, this was not the case and a simple turn of the bridge screws lowered the action while keeping the bridge flat. No shim needed in the neck pocket or pickups. The tuning issues were resolved by the tech replacing the nut clamps.
