Your pedals, first of all, I think you have confused. I'm not sure what the damper pedal is (assuming you mean the sostenuto pedal) is actually the sustain pedal, which holds out every note you play (sounds slurred). The best recording would be a mix between the first and second mp3's, leaning more toward #2. However, in between pedalling, lift and re-articulate quicker, that way the notes don't slur between measures but there is no real audible pause in pedaling. A.k.a., each time you want to redo the pedal, lift and press instantly, like a hiccup.
