Moving to Jakarta

Hello everybody :)
I will really appreciate if you can a bit orient me about Jakarta and living there. I am moving in three weeks and I'll do my internship till February.
I am curious what is necessary and very important to know before I am there ? I am wondering about all practical information like the weather, clothing (what is more common jeans/pants/shorts or dresses/skirts), should i bring few pairs of high heels....food in Indonesia? (Last days I have on a back of my mind that I should do vaccination against food bacteria) and what about safety? oh yeah, and what also I've been curious is if it is possible to find very nice places for clubbing, parting, fine dining and etc... I am so lost now... I've been living always in the west part of the world...

I hope I wilder from you!
Greeting from Amsterdam and best regards,
Mila
