I'm not sure if the spear sharpening is limited by anything, possibly intelligence or perception - I'm just guessing now, the thing is that you notice that his spear "is a little different", your character does, he says it in dialogue.
Anyway, you're really getting detail-oriented now, worrying about flint for a spear that you will only barely use
As for the stats exactly, it's role-play, like I said, ANY combination of stats will let you finish the game, and some people (me included) have had considerable fun trying to beat it with Intelligence 1, for example (this basically renders you a litteral retard, and still (barely) able to save the world!)
Also, FO2 is made for replays, so, just put together a character build that is "sortof you" and play through it - and don't get too upset if quests dont work out ideally. It *is* roleplay, so unless you have a good save-file to resque you, just add it to your character's history. In my first playthrough I managed to cause a complete and utter tragedy, arguably one of the worst quest-resolutions in the game... and ever since, I always solved this quest so... correctly... and ever since I always miss that feeling, of having inadvertedly caused such a tragedy
