I've done a bit of quick searching on the web and I'm having trouble finding information on how to add your own sounds to your map. Does anyone have any pointers? Thanks.

You can either include the sounds in your .rar file with the correct directory (should be in /sound/ and your map in /map/), or you can PakRat your sounds into your BSP so there is only one file you need to worry about - and is a much better idea. Check the Useful Links sticky for a link to PakRat.

Got it working, thanks. That's so simple, no wonder I didn't find much info on it!
