How to train with Developers Board and modules?

I have Developers Board and 3x Digi Connect Wi-EM modules.
What are the opportunities to train and develop with these deveices?

I don’t have a wireless internet at the moment(only wired LAN) . Do I have to install a wireless gate to get an Access Point?

If I would like to use ad-hoc mode would I use the developers board with digi module and the other device would be wireless card on the same PC? Or should it be on the other PC?
Can I make ad-hoc network with 2xdigi Connect Wi-EM on the same PC? First with developers board and secend directly by RS232.

I’d be greatful for advices about possibilities to exercise.

Sorry for my english.
