As obviously resignalling removes the trainstops and replaces the interlocking, and I'd have thought they'd maybe use that as an opportunity to replace pneumatic points too? And if so, presumably this required all the P-gates which run off the air main to be replaced at stations?

Trackside air mains are still in existence on sub-surface Lines, pneumatic points are still in existence at some locations:
High Street Kensington
Edgware Road
Aldgate East
Plaistow
Dagenham East etc.

The outdoor sections of the Central line no longer need the air main; I don't know if it's still kept pressurised though.
