Newcomers in Finland (Helsinki)

Hello, there!
My name is Konstantinos! I am a new on this web-site!
My family, that is my beloved Korean wife and my beloved daughter 12 y, we will come to Helsinki in Feb 9.
I am looking for a job, a place to stay and a school for my daughter.
I have so many questions for Finland and the Finnish people as well as what do I need to do first for being integrated into the Finnish society.
Please help me with your suggestions and experience about life there!
Thank you so much for your help!
