Hiya! I would ask all those questions to the people who have the kitten, as they are the ones with all the knowledge of his/her personality etc. I know (from asking on here....) that a kitten needs his/her first vaccination at 9 weeks but that the little kitten shouldnt be leaving his mum ideally until 12 weeks, although alot of folk do let them go younger, he/she needs to be fully weaned before he can leave mum. Good luck!
