"Should I be worrying about bathing her right now?"
From the picture I'd say you're concerned about the wrong sentient being getting bathed...... ;-)
Most pups are pretty resistant to both poison oak and poison ivy, but they can certainly pass the oils that cause the rash from their coat to your (or your family's) skin, so you might want to give her a quick bath for that reason alone.
Do watch your pup for red inflamed skin, itchiness, or raised bumps or swelling on the skin, which would mean she's having a reaction herself. If you see any, take her to the vet.
