It looks like an interesting bike. Not real expensive. But, quite "flashy". Get a good lock for it if you're doing commuting.

At one time it would have had front and rear canti brakes, which were replaced by linear pull V-Brakes in the rear, and simple older dual pivot brakes in the front.

If everything works right and satisfies your needs, then just use it as-is.

New tires when you eventually need them.
