There is no defined service interval for the timing chain. If it is making a lot of noise or you are getting timing related check engine light errors, you should replace it. People have driven over 400,000 miles on the original chain without any problems.
1998 and up 4 cylinders have timing chains not belts, which means it is not necessary to replace.

No, it has a cam belt. Replace every 90,000 miles.

I just replaced the timing chain for my 2000 Camry. I did the same thing for my last Camry, a 1996. The timing chain goes after the water pump bearings fail and jams everything up. Then I had to replace the timing belt, water pump, and all belts.
2000 Toyota Celica have timing chains.
I recently replaced the timing chain on my 1994 Toyota pick-up. That cost me ~$800 parts/labor.
