Wireless: Atheros AR9285

Could you please tell me what version of mac os x, i can use and that kexts that i need to to use.

Altheros cards are problematic, you might need to replace that to get it work proper. About the HD 3000, please check if there are drivers for this first or you might end up without proper graphics and frustrated.
