Audio Production Software?

I am putting together a mini studio. Currently I have FL Studio 7 for my production software as well as a midi controller with mpc pads. I have downloaded the freeware Audacity as an initial voice recording software and I also have Abelton Live Lite which came with my controller. Are there any other software that you would recommend I get ( I know about Reason as well as Sonar/Cakewalk)?
