I want to take in a feral kitten thoughts?

I'm in love with one of the neighborhood kittens. She is a tiny 2 month old maine coon/angora mix. Shes a ball of fur and so sweet. She's already on solids since I feed her and her siblings. She is the only one who likes being picked up. Would it be okay to adopt her and tame her? I have a 5 month old angora kitten and a small chihuahua. What would I need to do before bringing her into my home. I was going to take her for her first shots and a flea dip. I supplement the dewormer. My vet gave me a huge bottle since I rescue kittens.
