You can assign the other races their points if you like, but they do it on their own if you don't, it just doesn't show up in the race selection screen, but the bonuses are there after you start the game. You can look for yourself by running the game in cheat mode and switching to the race using the hot-seat key combination. Look at bonuses in the stats and graphs section of the civ manager. There's some other interesting customizations you can do on the races from the edit button on the race selection screen just prior to game start. Look under Personality.
The races do have much more individual character in TA than DA, enough that you sometimes forget they're just bits and bytes running through a processor. Sorry I can't tell you where to find any documentation on that. Though, it should become obvious after you've played a few games.
Have fun!
