1- Try Autozone.com
2- All you really need is the water pump gaskets... But usually people replace the waterpump seal & opti seal while they are there because they are easily accessable when you have the opti off.
3- The only part you need is the flywheel, but once again, since you are going to have the trans out, some people would replace the rear main seal.
