What you're looking for is the SRD, which means the "System Reference Document" i.e. official stuff. Here's the link. Here's also a quick-link to what the spells do and such, along with other spells of their level.
Admittedly, it'll be hard for you to just be a lightning throwing sorcerer because there are only so many electrical based spells you can pick from. That being said, if you want to be a pure evocation blaster-caster, that's totally doable. The fact you favor lightning is just a quirk.
The only reason I'm being nitpicking is mostly for balance, since things Lesser Teleport essentially means "Fuck your cage" or "To hell with gravity". And that's a cantrip. With a bit of creativity, you can do some massive damage simply by teleporting above your target, dropping an object as a free action, and teleporting out.
