The Hord - What should I buy???

[Mordread]

Hi there,
I'm totally infected with Eden. Love the game. I'm playing Bamakas, but I also have some other starter's here around (eg Matriarchat and Resistance). My wife will start playing Askaris.
And I want the hord, too. But I don't know which models to buy. I can't find the cards to download. here some questions:

Must I decide to play with the broodmaster or the beastmaster? Can I mix the two starters?

With what models plays the master of flesh and the butcher?

Can I play every npf?

Can I play the bayakoye? (I love the model)

Are there restrictions playing models. For example can I play a second mireling?

And where can I find the cards for checking the ablilities and the points?

Thanks
