Changing a timing belt on an interference motor is always a good idea. I've done it on two FWD cars, it's a severe PITFA.
If the timing belt jumped a tooth, you'll want to replace the tensioner too. But if it really did jump a tooth, it should have also thrown a code. You can check visually: pull the viewing plate off the timing belt cover, spin the motor till the little marks on the cam gears line up. If you can't get them to line up, it did jump a tooth. If they do line up (at the 90 degree position), check to see if the mark on the crank snout is lined up with the scribe on the balancer, or block, or cover, or wherever the hell it is.
