as you guess from the subject i'm a lefty and i want to build myself a
traditional style workbench, most i've seen have the tail vice on the
right, would i be better off building it arse about and putting the tail
vice on the left so that planing is against a fixed dog instead of
pushing against a tail vice.

Yes.

Advice from another lefty :-).
