I think extensive research through the internet and pet stores may be the most useful in these situations just to be safe. I can tell you though, when I was getting a new kitten the way I went about it was getting them familiar with each others scents first.
By this I mean, we had my older cat Lucky in one bedroom than would let the kitten run around the house and sniff at the door and such, than we switched and had the kitten in the bedroom and Lucky on the outside. When they seemed to be handling that okay we got an old Dog play pen and put the kitten inside that with one of us with her and had Lucky able to roam around on the outside. This allowed them to get near each other and see each other without having actual contact in case they didn't take too kindly to one another.
This method seemed to work out alright, and my cats had gotten along ever since. Of course this method might not work for everyone and you should go about it in whatever way you are most comfortable and to make sure both your cats safety comes first. Hope this helped with at least some other ideas of what you could do, or how to go about it.
