BTW, what does flux do and how do I use it?

I don't think lead is that bad to handle, just don't lick (solid or liquid form), eat (solid or liquid form), or inhale the fumes (gaseous state (you need a hot torch to get lead hot enough to change into this form (1749°C (3180°F)))) of lead (Pb) That said washing you hands is a good preventative measure (nobody wants to get lead poisoning). Keep the solder away from kids and animals. Also the fumes coming off the iron and solder is not that of lead but the chemicals of the rosin core burning up (this may be 'safer' to inhale then lead but that said DO NOT BREATH IT IN). You don't need flux as it's built in [rosin core]. The rosin core remove impurities which increases mechanical strength and also improves the electrical conductivity of the joint [Therefore you have a strong joint with a good electrical connection]. You really don't use rosin core, it works on it's own automatic when you solder.
P.S. I do hope you are washing you hands regularly, anyway. If it's avoiding lead poisoning or just the flu, best to wash your hands.
