Hello and welcome to LQ!
I remember a long time ago I started recording within linux, and it wasn't all that bad. Instead of trying to list all of the software, check this link out - http://briansbedroom.org/
Later on, if you want to, shoot me an email and I can let you know what software I currently use, as I'm not on my computer right now.
Cheers and welcome to LQ again!
