Yes, ivermectin horse paste would be OK (injectible ivermectin PLUS would be best). In her case, I'd suggest treating her once, then 10 days later, and then 10 days after that. Essentially to attempt to wipe out the infestation and get all the stages of worms. Goats need higher doses than cattle, sheep, or horses to be effective when it comes to mg of medication per kg of animal weight. They metabolize the medication faster than the others, so to be effective, they need more.
Here is how to dose the horse paste.
As for minerals, any loose minerals labeled to be given to GOATS not sheep will be fine. A sheep mineral will not have the amount of copper that a goat needs to survive.
