It's established by Lucasfilm that Palpatine is Sidious (Remember Dooku saying a Sith was running the Senate? Plus, the same actor portrays both parts. ). Still, I don't think the Sith have recruiters out there scouring the landscape for frightened or angry children to exploit, since the Sith are few (only two exist at any moment) and have been hiding out for centuries, until The Phantom Menace when Sidious and Maul start up their new endeavor. He was taught by whomever his Master was, way back when. As far as the lightning thing goes, I think that's a Sith move, kind of like how they uniquely use red lightsabres.
