This depends on the quality of the violin. It is best left to the professional restorer as the varnish is difficult to match and may be either spirit or oil based.
Cosmetically and in terms of resale value yes. Scratches will not affect the tone.
The varnish is really more superficial; it is simply a shiny coating over the wood of the violin but does not serve as much protection to the instrument itself. Though it may protect the instrument from very light surface scratches and scuffs, it will by no means protect the instrument from more serious damage. Even water can ruin the varnish on the violin--so no, varnish is not very protective.
