When should I replace the cam belt on my Subaru Forester?

I have owned a Subaru Forester 2006 (non turbo) since new and it has been very reliable. I've noticed that the cam belt hasn't been changed since 57,000 miles - the current mileage is 152,000. Do I panic and get it done now?
Get it done, plus tensioner, plus waterpump, but by someone who knows Subaru engines, not just any jobbing garage. First question for the garage should be: how many of these have you done before?
