I just resently did my timing belt and I'm pretty new to mechanical work.
I started out by reading on the forums here, and also I downloaded the service manual which helps a lot. Grab a friend that knows a bit more than you and do of to it. It's pretty straight forward that some one with our knowledge can do.
P.s. I ordered the timing belt kit off eBay which had the belt, water pump, tensioner, and new gaskets for what you would be taking off and putting back on.
