1,2 ) It's a big adjustment. Move the crate into your room, they like to be close. Take her for potty walks a couple times an hr, pick her up, go outside, smooch, put back in crate. You will be exhausted, but within 3 weeks she'll be trained. Ignore screaming during the day, at night consider it a cry for potty unless you just took her out.
3) Feeding in crate is fine, but also, vary this outside the crate too. You acclimate her to the crate by not over using it during the day nor only when you're away (which pairs the crate with loneliness). Leave the door open, make sure there's lots of soft blankets in there, special crate only toys, and let her go in whenever she wants to play or nap.
4) They like and need to be close, so sleeping on you is fine. The task is for you to be in control of that, so sometimes put her in the crate, door open, in room with you, to nap and come out and find you when she's up.
