3. The air-con is not working and the compressor is missing a belt. What belt do I need and what else should I do to get it working? Will this get the rear-window heating to work too?

You can buy that belt from most auto parts places, ie. Repco or Bursons, just tell them you need the A/C compressor belt for AE86 Corolla. No, this won't fix the rear window demister if it's not working now.

Manual recommends 1.7kPa tire pressure but it looks just a slightly flat compared to other cars - is this a good pressure? I have the pen-guage and the gauge on a foot pump and they both show different readings (I feel like the pen is more trustworthy)

I'd recommend ~32-36psi. 32psi=~220kPa. Are you sure it's 1.7kPa? at 1.7kPa the rim should be rolling on the ground.

8. There is a gut wrenching(!) grinding whenever I try to downshift to 1st gear (no matter how I try to engine-match), which is why I don't, unless it is travelling really slowly. Is this normal?

Yes, it's normal. First is a very short ratio, you generally can't synchro into first over about 15kph. Anything faster than this and you'll get acceptable response in second anyway.

9. Would the chassis of this 20 y.o car be strong enough to be a track car (that is after future upgrades) or do I have to sand the surfaces the whole car to metal to find out?

Um, no, you don't need to sand it because all you'll find is sheet metal, which you know you'll find anyway. For track applications (involving repeated applications of singificant forces) structural rigidity is a good thing. This can be acheived by stitch welding the chassis together, fitting structural braces, or welding in a roll cage. The improvements are all relative, though; if you're just starting out, you'll have heaps of fun in your stock AE86.

I read somewhere that these cars have rear drum brakes - how can I tell? I saw shiny disks at the front when I took off the front wheels which makes me think its has front-disk brakes instead! Are disc brakes better? What do you think of upgrading to 4 wheel disc brakes?

Further to what Satoshi has said, note that because your car has front discs doesn't mean it can't also have rear drums.
