Rann sèvis bay chagren...?

Yes, ...an expression: being a good samaritan causes grief.

Ou pa ka atann pou tout moun rekonesan lè'w ede yo.  Gendefwa ou ede yon moun, enpi jès la tounen yon fwèt pou kale'w.  Si w'ap rann sèvis, fè li pou satisfaksyon tèt ou oubyen pou lanmou Bondye. Pa atann ke moun ou ede a va vin bobo pye'w.  Si'l fè sa, anfòm!  men si'l pa fè'l, se byen tou.

Do the words ¨vin¨ and ¨vini¨ mean the same thing? Are they used in different cases?

Vin is a contracted form of vini
They both translate to come, to become, to arrive, come forward, etc...
The contracted form cannot be placed at the end of a sentence.
For example you'd say: 
Se pou w vini. 
instead of:
Se pou vin.
You must come.

But you CAN say:
Se pou w vin wè mwen.
or
Se pou w vini wè mwen.
You must come see me.

Can you explain the (subtle?) difference between "Li t ap pase pou l-al kay fanm li" and "Li t ap ale kay fanm li." Do these sentences require "nan" for "nan kay fanm li"? Why or why not?

Li t'ap pase pou l'al kay fanm li.
He was passing by to go to his lady's house.
He was moving past here in order to make his way to his girlfriend's house.

Li t'ap ale kay fanm li.
He was going to his girlfriend's house.

No, these sentences do not require the prep. "nan".
In ale lakay mwen (going home) or ale kay yon moun (going to someone's house), the sentence without the preposition "nan" best describes the motion of moving into a direction (towards home, in this case).
If you were to add "nan", the sentence would translate He's going inside the house or he's stepping inside the house.
