Gopal,
There are 17 pages of threads if you run a search on "timing belt". Two that seemed interesting were:
Ken4 had a good thread for a 2000 Camry http://www.toyotanation.com/forum/t109966.html
Tracyf”s 1990 V6

Even though they aren't your model they are informative.
Parts I would consider: water pump, oil pump gaskets (shaft seal & gasket), tensioner pulley & spring, main seals (cam & crank shafts), and valve cover gasket (why not). Replacing the motor mounts will give you a better feel and may help reduce wear on other joints. I read somewhere that bad motor mounts would cause hard shifts from park to fwd or reverse but I don't know if that is true for Camrys.
