The timing belt is fairly simple on that engine. The hardest part is removing the crank bolt. We have a big 3/4" impact and that doesn't even remove them some times. There is a special tool that holds the pulley from turning while you use a breaker bar and a jack handle to snap it loose. I recommend doing the t/belt, tensioner, water pump, drive belts, and possibly tensioner/idle pulley if they are bad. You will have to spin them once the t/belt is off.
I've done so many of those I can do it in a hour or so. I would recommend some kind of repair manual preferably a factory one from
