I'm pretty sure you've got to do it at every sink, bath, etc. - across the hot and cold, and bridging that plastic connector. (Not sure about the flexi-pipes - you might need to bridge those as well.) But anyway, as you say, the electrician should be able to confirm one way or t'other. Anyway, it's a pretty small job compared to the plumbing. :-)
Tis correct, and is called 'Equipotential Earth Bonding'.
Hot and cold taps must be bonded with a minimum 6 mm2 cross section cable, so that any leakage to earth will a) blow a fuse, and b) cannot create a dangerous voltage between any two fittings that might be handled at the same time with wet hands. The rules also apply if plastic pipes are used.
The earth terminal on any socket outlets near to the sink should also be bonded to pipework with 6mm cable for the same reasons.
