equipment info please!

ok, so I have the discs, books, Bose tower & bases, great mics, and I'm ready to upgrade to laptop and downsize equipment; I have the plexwriter, and understand (basically) the programs offered. But what do I use to connect to the pc to use multiple xlr mics???? What kind of line out do I send to my Bose amp from the pc to hear music? If you are going to tell me it's in the thread, care to show me where? I sure am having trouble finding it. Thanks
