Welcome! Don't worry about the alpha thing now, just give your dog some time to settle in. If he is playful work with that to built trust and love, give lots of praise to good behavior. The cats may take a while, hopefully they will stand their ground. For now you can redirect your dog away from the cats, maybe a tab leash will help, calm him down, rub his chest, when he's calm and non reactive try giving a treat.
