>>Looking for a software that can allow me to take "kyrics" out of music
Assuming you mean lyrics, then no good solution exists yet AFAIK. You can get reasonable results on some tracks by using something like Audacity and reversing the phase on one of the stereo channels, BUT this assumes that the vocals are mixed to the centre. Also, you tend to lose the bass as this tends to be mixed dead centre.
If you think about it, removing part of a mixed track is like trying to take the sugar out of a cup of coffee.
For your other stuff, try Audacity to start with. It supports VST's so you can download masses of free effect plugins (vocoders, flangers, reverbs, phasers, echo etc etc).
