First up: if your 1210 is a Mk5g you will not need a rewire.
If is a Mk2 or a Mk5 it is a good idea to rewire.
70 quid seems pretty good for internal and external wiring - it is a pretty tricky job, I would go for that. If you are twitchy about the wire he is using you can talk to him about it and maybe agree another - I know Cardas is popular.
Length of wire: usually two meters is just fine (occasional issues if unshielded). However the signal from the TT to the phono stage is tiny, so I think it is better practice to keep that shorter and have extra length elsewhere.
