I use a programme called Adobe Audition. Its great for working with audio it has lots of speciallised tools for cutting up tracks and also to go much deeper if you want to optimise your recordings. There are many of this type of audio programme Wavelab is an old one - I think they are generically called 'Wave Editors' - probably quite a few freeware ones to download on the internat if you look.
Good luck and we all look forward to the spoils.
