You will have to set up your modem manually, as pci modems use non-standard serial ports (usually /dev/ttyS4, Com5 in DOS terms), look in windows to see which serial port it is set up on and then set up the corresponding serial port in linux. Do some searching here or on google, you probably should have the actual modem model number handy.

As far as your SB-Live card, again you'll have to do some searching.

you'll have to use the sudo command from a terminal window in your X session to run a command as root, ex:

sudo sndconfig

to run the sound card configuration tool

or you could press <CTRL><ALT> <F2> to go to a root console and run root commands from there, then press <CTRL><ALT> <F5> to get back to your X session.
