You could start with something like this. I can't find your model car in the US, but you aren't in the US so I guess that would be why. Also, replace the transmission fluid/filter/seals. That plus regular maintenance like listed above is the first step.
Let's see if we can keep your car from catching fire before worrying about the lights and capacitors. I'm glad you aren't a student. This will take some work.
