Κindergärtnerin Ausbildung

Hi,

I'm looking for  informations.
I'm nineteen years old, I'm from Greece and I have German roots. 
I want to study kindergarten(Κindergärtnerin) in Munich.
I know that maybe this site is not responsible for this type of informations, but I thought I can get a help from here (cause I really need someone to help me), because the informations that I got from some centers (institutes, information centers, embassies and other) were not sufficient.
So,I already know that you don't actually study this field of ​​education at a university, in Munich.
But I have so many othe questions and maybe..someone here knows.

So I wanna know:

-How many years does it take to finish your training / studies (AUSBILDUNG) in kindergarten?
I've heard that it's like 2 years for a Kindergarten ASSISTANT Teacher, and 5 years for a Kindergarten Teacher (I mean kindergärtnerin )

-In the end of this training/ studies, do I take a diploma/degree/certificate?
If yes, Is this degree  acceptable and in other German states?
And wider in other countries?
Αnd will it have some low value because it's not a diploma from a University?

-How can I participate in this training / studies?
What do I need?
What level of german language do I need?

-With this training/studies do I have some possibility of being housed in student residences or something?

-In these studies are there any tuition fees, or any payments?

And finally
If you can't help me, In Munich, is there any competence center that is associated exclusively with kindergarten training / studies, and with wich I can get in contact ?

If someone knows something, a site .. or anything else ..that would be very helpful.

Thank you.
