LW, there are several problems here, the original answer addresses one, and "how do I handle what my loudmouth dad says around my kids" is another one (beyond my paygrade.)
But the answer to "I want to teach my kids about evolution but I don't know anything about evolution" is to sit down and learn with them. I don't have any resources at hand but I know they exist and I can help you find them if you want. Either Cosmos series is a good start, not just for evolution but for the basics of how science works that let you understand evolution. Learn together! "I believe in this thing but know nothing about it" isn't actually better whether it's science or the bible.
(That said, you won't learn the gotcha answers to your dad's arguments because they don't exist, you can't argue creationists out of it with science. Either trust that your kids will learn from you more than him no matter how much he talks - once you try to learn with them - or look up actual strategies for that. The simplest one is to just ask him to defend his own beliefs. "Oh, can you explain to me how 40 years of going to the zoo is the same thing as all of the history of earth?" "Do evolutionists believe Adam and Eve were apes? Can you tell me more about how they think that works?" And be sincere, not confrontational! Just firmly make him actually address your questions, not swerve it somewhere else.)
