Essentially, you need to decide what you want to achieve with your letter.
If you mainly want to let off steam and heap abuse on your inconsiderate neighbour, you are on the right track. In fact, I would even suggest peppering a few additional insults throughout your prose, just to get things properly out of your system.
On the other hand, if the result you seek is a change in his behaviour, you would do well to avoid arming your letter with irony, humiliatng phrases or an obviously bossy tone. Put yourself in his position for a moment - how would you react to being told off by your neighbour as if you were only nine years old again?
In my view, your best bet would be to remain polite (addressing him by name would be a good start), explain the situation clearly without going overboard, tell him in concise terms about the effect his behaviour is having, and ask him to stop.
At this stage I would avoid any threats of reporting him to management or the like. First give him the chance to mend his ways of his own accord - he may have no idea of all the angst he has been causing.
