If your working with different races, one of the first things to consider is the impact of their different ability mods on their culture.
Take a race that has a +2 to wisdom lets say. That means the average joe shmoe guy has a 12 wisdom. That means on average the entire race is better at sniffing out lies than normal humans...so there culture will probably value honesty. They are very perceptive people, they can see things farther than other people...but they also pick up on emotions better (sense motive).
They are mentally resilient, able to take mental stresses better than normal. Add all that up and you have the beginnings of a culture.
