It's immature and irresponsible.
Surely there must be an adult on here who is knows how to fit down lights in sequence and is intelligent enough to provide a few simple steps how to do it.[/quote]
Really,
You say it's immature and irresponsible, yet it is yourself you describe.
You have been told get an electrician, surely you are intelligent enough to realise that what you propose to do is illegal and potentially very dangerous not only to yourself but the poor people above, that you are putting at risk.
You say you have had it checked out about your fire rated ceiling and it is ok.
So many people will say that just to get help and then go and ruin it by doing an incompetent diy job no matter how good/ capable you think you are.
I have been to many a job carried out BY A COMPETENT DIY'er that has been an absolute disaster waiting to happen.
LIVE BY THE SWORD DIE BY IT !!
