Been there numerous times, both by water and by land. For attractions you`ve got the Pacific trail, but see your bear question for further clarification on that. You`ve also got the Aquarium and Visitor center which might be enjoyable but if it`s nightlife and wild times your after you might want to give the place a wide berth. They`ve got a couple of sports bars but given the population they likely aren`t all that busy unless it`s tourists.
As for the bears, don`t worry and just be aware there aren't many in town since most of them tend to do their shopping and partying in Tofino.
Good luck and don`t forget to pack your rain gear.
