I like your goal, but I would start with something more manageable. Perhaps a car that has an external water pump, or one that just needs a set of plugs. These repairs you mention are critical and if ANY mistakes are made then you could blow a motor. I would bet that this would be the outcome unless you have someone with experience to help you.

If you must proceed, here are a few suggestions:
1: Get a haynes or Chilton Manual for this car.
2: Valve stem seals can be tricky for a novice unless the heads are removed.
3: The timing belt is fairly straight forward.
4: Do you need to rotate the cam? Just put the pully on the end finger tight and use a strap wrench if needed.
5: Please consider learning engine basic operating principals on a smaller/cheaper engine. Like a old lawnmower motor. You can learn how the parts must interact in timing, ignition, and fuel. This is good because if you screw it up you can rebuild it in an hour or so and it will not cost much or leave you stranded. If you work on your car motor and then you AND your friends get stuck somewhere you won't hear the end of it. We are always here if you do go ahead, but a lot of mechanics is done by feel and little details(like the direction to turn a nut) become instinct that we may forget to mention. This could cause you a lot of problems.
