wireless networking

There’s a closet on the other side of one my bedroom walls where i have my DSL modem, wireless router and cables and such running to different places in my house. I took an old desktop pc and connected it to the router so i can store files, and i drilled a hole in the wall and connected my USB printer (and set it as a netowrk printer) to it so I can print wirelessly…

Is there anyway I can take over USB ports or maybe the sound card from my laptop so I can connect it to my home theater to it and play music through it wirelessly?

Also, is there any wireless mice that can transmit straight to my wireless card in my laptop so i don’t need a reciever or dongle? my wireless mouse now has a usb reciever with a 6 foot long cable… I just want to clean some stuff up

thanks
