Just an FYI: holding your breath does not negate the poison.
Poison rules:
Contact poisons are contracted the moment someone touches the poison with his bare skin. Such poisons can be used as injury poisons. Contact poisons usually have an onset time of 1 minute and a frequency of 1 minute. Ingested poisons are contracted when a creature eats or drinks the poison. Ingested poisons usually have an onset time of 10 minutes and a frequency of 1 minute. Injury poisons are primarily contracted through the attacks of certain creatures and through weapons coated in the toxin. Injury poisons do not usually have an onset time and have a frequency of 1 round. Inhaled poisons are contracted the moment a creature enters an area containing such poisons. Most inhaled poisons fill a volume equal to a 10-foot cube per dose. Creatures can attempt to hold their breaths while inside to avoid inhaling the toxin. Creatures holding their breaths receive a 50% chance of not having to make a Fortitude save each round. See the rules for holding your breath and suffocation in Environment. Note that a character that would normally suffocate while attempting to hold its breath instead begins to breathe normally again.

Also, I would recommend Latrine's profile for a well spelled out character build. All of the work is readily present. Even the break down of a Giant Scorpion into a tiny creature :)
