You will need a service manual on this car, like a Haynes, Chilton or Alldata (I'm assuming this is a 2.7 liter) to really help you get this done right. The pictures in these books will help more than words alone. While you're in there, check the water pump (regardless of engine) and replace it. There are a lot of steps to get this done right, like purging the tensioner plunger (if installing a new chain) and lining up the colored links to the sprockets, etc. Again, this is not an easy job and you will wreck the engine if this isn't done right. In the meantime, don't move the camshafts or crank.
If this is a 3.5 liter, your job is going to be easier, but you will still need a manual. I would not return the used chain or belt to service as you're asking for trouble if you do.
If the timing chain is off, you will probably have bent valves.
2.7L has a chain 3.2 and 3.5L have a belt. The chain does not have a service interval. Replace the belt around 100,000 miles
With a special puller.
