You might look at the Stormborn Sorceror Bloodline from APG.
Good thematics, will up the SaveDC of Shocking Grasp by 1 as well, and has a lot of other neat zappy-themed abilities.
Finally, if this is something you want to use frequently, I highly recommend Spectral Hand as another spell, so you can do it from safe distances.
You can also look at "Shock Shield" and "Shocking Images" as great spells that will help with a build with this theme as well. Shocking Images are a nice way to deal damage during your opponent's initiative if they do find a way to close to melee with you at higher levels. It will definitely make them think twice about continuing to swing, when they aren't hitting you, but still getting zapped every time they try.
