New Kitty! Any tips on introductions?

I just got a kitten from work. One of the vets found them, they were strays, but have come around nicely. Anyway, they were in need of homes and Dave agreed that we could get another cat. He's home now, and Sage is being decent, she's not attacking him or anything, but she wants nothing to do with him, which I know is common. She hisses if he gets too close and observes him from her cat post which is on a "breakfast bar" type of counter that is in between the kitchen and computer room that he can not reach. I know eventually they will get along fine, Sage is only a little over a year old, so she is young enough to adjust. But any tips on making her feel more comfortable? I gave her treats and a can of wet food all to herself to make her feel like she's still loved (which she is). I know I can't hurry the process of them getting to know each other, but I just would like some tips, stories, opinions, etc. THANKS!!!

(PS - Wanted to add that the kittens have been there at the vet under observation for almost 2 weeks now and have been tested for FIV, FELV, and worms. Shots come next week, yay, the fun part :roll:, lol, they are 8 weeks old)
