Saravia: 1.- Congratulations... I am proud of you..
2.- You can take a look at Musix or Ubuntu Studio most of the software, if not all, that is installed there is also in the Trisquel repos so you can install it with apt-get.
However, I suggest going with parabola for most up to date software. This type of software is constantly improving. And for someone used to proprietary is better to go with the best.
