Yeah, tapping and sweeping are invaluable skill, and its better to start now cause itll take a while to perfect those. But about solos, "Knocking on Heavan's Door" by Guns n Roses. Both of the solos are pretty easy and shouldnt take much time to learn. And if your into Green Day, there remake of Operation Ivy's song "Knowledge" has a pretty awesome solo in it, you should definatley give it a try.
