I would go perhaps poke about the wikis and websites of some games that have extensive combat code that handle that side of things to see the types of stuff they do; there are tons of games with combat code that does the big, heavy lifting of that for you.
If you're going to make the social side of things work, my one advice would be: make your social stats matter on character vs. character interactions. Then you can figure out what bonuses your social Perks confer. But I think you'd be better off doing custom work, looking at perhaps some of the Fallout game mechanics outside of the SPECIAL thing. Crib from places. Look at say, the Buffy RPG which has some nice mechanics. Look at things, find things you like and that you think will work and crib heavily.
ETA: The combat side of things, just glancing at the Fallout wiki, seems like it would be relatively straightforward. I'd go look at TF2k5 and Megaman MUSH's wikis to poke around their combat systems; you won't find the code (though I'm sure you could ask their staff, particularly 2k5), but a lot of the stuff I'm seeing with temporary buffs/debuffs, various benefits of each stat level and such is really doable in my experience with combat systems.
(Also, I'm going to liberally lift stuff from here; there's some really nice stuff I can convert into powers for my own game).
