Unless it has been extended in the last few years, that is a pretty short runway, so braking would be fairly hard, especially for a 300 compared to an NG. How much smoke was seen and at what point would be interesting - I have occasionally seen brakes smoking when a 73 has rocked up on stand, and while it shows they're pretty hot, it doesn't signify much more than that unless the smoke is profuse. I think I'd be inclined to have the fire crews come out but not to evacuate unless flames were seen. Still, hindsight is easy and it's always better to err on the safe side, especially with smoke and fire.
