Toyota Repair: Toyota Camary Timing Belt, air impact wrench, toyota camary

Question
I have a 1998 Toyota Camary with a 4 cylinder engine.  I need to replace the timing belt.  I would like to do the job myself.  I have some mechanical experience, but not with Toyota vehicles.  

1.  Is there anything unusually difficult about changing the Camary's timing belt?  

2.  Any other parts I should change at the same time?

3.  Will I need any "special" tools for the job?

Thank you for your time and experience>

Answer
An air impact wrench would help to get the crankshaft pulley bolt off, they can be pretty tight, you can also loosen it with breaker bar but you will need to hold the pulley, a chain wrench works well for that.
If it has more than 90,000 miles I would recommend changing the water pump at this time and the cam and crank seal, if they should leak after you replace the belt you will have to take everything apart again, other than that it's fairly simple.
