Aaron. Dude. Relax, you're going to do fine!
I'd lose any questions on that sheet that you aren't 100% sure about, that are superfluous or too detailed or whatever, because too much reading material for your class while you are speaking will only distract them from what you are saying and it may throw you off too as a result. You could hand out the sheets, give them a minute to look at them, then make clear you want their attention for the lecture and after that give them another minute. Discussion about them afterwards is a good plan!
Good luck mate!! You know I'm just like you in this respect... sigh.... I have an essay on Literary Theories to write and haven't put a single word to paper. Oh well... it's all in my head I tell you! I just need to write it out
