14 Int - it lets you read books a lot easier and increases the rate in which you gain skills without books.
Nearsighted, Insomniac, Heavy Sleeper - these are practically freebies but will bite you if you're careless.
Quick, Packmule, Fast Reader - these are nice for a new player, but not vital for experienced players.
Light Eater, Quick Learner, Inconspicuous - these are a bit less helpful to new players, but many experienced players find them vital.
Schizophrenic, Mood Swings, Chemical Imbalance - pick these if you want to play "hardcore mode".
Addictive Personality, Trigger Finger, Weak Stomach - can be free points depending on how you play, but may cripple you.
Strength - Melee is silent and windows are common, no reloading either, but you're generally low on storage.
Perception - Guns are loud, but handguns are point-blank are fatal and rifles will one-shot most anything. Wear two backpacks for massive storage.
Dex - It helps, but not greatly.
Skills - One point in Dodge is really all you need, and that's optional. You can learn all skills through practice, no need to waste points!
You'll notice that I focus more on bad traits than good traits. If you have more bad points than good points, then you can get better stats, giving you better int and better str/per.
Most importantly though, find MP3 player, find TONS of batteries, and find tequila. You only gain skill when you have exp, and you only get exp through having morale. MP3 players are essentially free morale, and tequila is a massive morale booster, take shots two at a time once or twice a day to avoid addiction.
