It sounds like you're doing great!
With Mallory, she is crated for about two hours at a time during the day when she is alone. My mother comes by three times a day to walk her and play with her for a little while. Otherwise, when I am at home or in my room on the computer she is out and about. She does great, lying on new bed, chewing on her toys.
I have a sturdy baby gate at the door and she already knows to paw at it when she needs to go outside and will do that most of the time.
Potty training is going very well. She drinks quite a bit of water so right now it's a matter of her not being able to physically hold it and we go on frequent walks. I tell her to "do your business" and she knows what that means now.
We've only had a few accidents and I contribute those to me. Even if she doesn't paw at the gate she sends me cues that she's getting ready to have an accident and it's just a matter of me understanding them and getting her outside.
You sound like you're pointed in the right direction! Good luck with your fur baby.
