Q 1:
Is it permissible for me to perform Hajj on behalf of my grandfather?
It should be noted that I was born after his death, and therefore I do not know if Hajj was obligatory upon him or not, but he died without performing it.

It is permissible for you to perform Hajj for your late grandfather, as long as you have performed it for yourself.
