Mettler

It's more than likely to be a timing chain rather than a belt, but you can only really tell by having a look. The timing chain housing is usually covered up under a plate at the front of the engine. Don't go pulling this off yourself, get a mechanic to do it. Usually this plate is part of the water pump housing, and you don't want crap to go spilling everywhere.

I dunno, that's specific to your vehicle. Jack the car up and wiggle each wheel side to side vigorously. There shouldn't be any play in the wheels... if there is, then you'll need new bearings.
Take a wheel off and remove the centre cap piece from your disc brake (if you can), and have a look inside it to check out you wheel bearing.

Well, points and rotor aren't exactly that bad. It's just one way of doing it. Just take off the distributor cap and look how worn away the metal contacts are inside the housing.

Check to see if the points are still flat on their contacting surfaces, or whether they've started melting & forming irregular raised spots.

Turn the engine over by hand (if you can) until the little cam inside the distributor housing is pushing the points to maximum cam lift, and then find out what your correct points gap clearance is meant to be, & use a feeler gauge ot check this.

If your sparkplug leads look old and cracked, replace them. 8mm leads are more than sufficient, I run 8mm leads on my modded V8.

Check your sparkplugs one by one... if they're really dirty, covered in carbon etc, then replace them. If they're mildly dirty, give them a bit of a clean with a rag & put them back into their respective cylinders.

You'll be amazed at the difference in performance and fuel efficiency with an engine that's got proper ignition happening.

If you're really worried about having points & a rotor, then fork out some cash for an electronic distributor unit. They just replace the innards of your standard distributor housing. It takes away much of the mechanical aspect of the setup.
