AZ box HD + : initial start

Hi,
I'm beginner with AZ-box and linux world;
I was able to load channels and connect AZ box to home network via wifi;
I have also tried to load some plugins like multicas, mgcam+sbox.
Firmware loaded is opensat.

Can anyone please tell me which is the best actual plugin/configuration working with opensat?
Can please also provide the related link ?
Are biss key already included?

Thanks and BR/Paolo
