Since no one mentioned where to actually get some of the things you need, I'll do so.
First off, IceCC 1.3 can be found at http://sfsrealm.hopto.org/dwnload.html#IceCC
As for the campaign sounds, you will need a filename list to be able to access them through WinMPQ. There is a package of these lists for various games at http://www.zezula.net/
In WinMPQ there is a tab in the options that has to do with setting up options for these lists.
