STOP and do some research
Sorry to say this, but I think that you may be about to blow away the value in what you have. Now, I am no expert in what you have - I do know something about Australian antiques, but this is different. However, my grandmother loved this kind of stuff and my mid-twenties son also loves it. It is becoming really popular and can be quite valuable. BUT, if you paint it you have blown the value away.
It is probably Laminex, probably over plywood for that age, and the doors are very thin timber veneers. Keep it as original as you can and you will keep its value. A very light clean on the timber veneers followed by wax. If you really must then perhaps some Danish oil (appropriate for the age). The Laminex will look better with a good wax - perhaps even something like Renaissance poly Wax.
Less is definitely more.
