A closed door is sufficient for quarantine. All of those things you mentioned could be signs of illness or just plain stress due to the new environment. He may also be constipated for a few days. All 4 of mine were constipated their first few days home. My F1 Atticus, who came home last month, didn't poop for 6 days. That was a record. I kept waiting for him to explode because a tremendous amount of food was going in the front end with nothing coming out the back. LOL.
Your purchase contract will probably stipulate that you take the kitten to the vet with 72 hrs of arrival for a general checkup. If you can get a stool sample by that time, all the better. If the kitten shows no signs of illness between that first general checkup and the end of quarantine, there's no particular need for a 2nd visit.
For the introduction after quarantine, I recommend putting your DSH in the kitten's room for a few hours each day for a few days and let the kitten roam the house and get used to sights and smells. Then if you have some baby gates, put them up with the kitten back in his room and let them interact through the baby gates until you see evidence that they are comfortable with each other. You can continue to switch them out -- putting DSH in the room and letting the kitten roam. You should play with both of them when the baby gates are up, maybe using a feather wand so they can chase it under the gate. Feeding them on each side of the gate is another way to establish trust. I'm thinking of your DSH in particular since she may resent the kitten and the change in her routine.
When you feel the time is right, let the DSH in the room with the kitten and supervise that first meeting. Depending on how it goes, that could be the end of the separation or it may take longer.
