New Guitar Player Tips?

Hey! Okay...I have been having an electric guitar for awhile (Fender Squire Strat) and now I've finally decided I'm gonna learn to play it. Haha...okay well I'm taking it home tommorrow and I wanted to know if anyone had any tips for me. BTW...I'm 14 and my dad is teaching me, and I have a poster that shows me the chords so I'm gonna use that to help learn them.O and what about any good rock bands with clean lyrics that I can idolize? haha jk..i know thats a little contridictory but there has to be at least one good band out there.
