Please shed your light - how to resolve those unknown devices

the hard drive of my lenovo thinkpad t60 came to the end of life.  i swapped in a new hard drive.  after installed window xp pkg 2, i experienced some issues:

(1) under device manager, there are a lot of unknown devices under "other devices".  windows can't find the drivers from local or web.  how to know what those devices are?
(2) no sound, apparently the sound driver is incorrect.
(3) intel wireless connection behaves weirdly - it can log on to non-secured wifi, but not secured ones.  it does not prompt for password, just keep churning.

here is the screen shot of device manager:



please advise.  thanks.
