I'm traveling from Guatemala to the US in March, my passport expires on August and my Visa is on that passport. I know Guatemalan citizens are not required to have the six month validity rule but I'm afraid the airline staff will not know this and won't let me board. So, should I renew my passport and take both the new and old one? Will it be a problem if the old passport is still a few months from expiring?

I'm from Argentina. When your passport expires authorities give you a new one and they do not retain the old one in any case. I always carry both passports with me, just in case I am required to show the old one.
If you happen to have a US valid visa on your old passport, present both documents.

No. Never heard that you need to wait until passport expires to issue a new one. It would be totally inconvenient.
