Ask WoW Insider: Best way to get instance invites?

It's time for our weekly edition of Ask WoW Insider, wherein we publish one of your burning questions for the WoW Insider readers to answer. This week's question comes from David, who seeks advice on scoring an invite to an instance you haven't had any experience running yet:
Ok, here's my question that I'm hoping gets a good response. For starters, I played WoW when it first came out and was a hunter then after getting to level 40ish I decided to reroll as a paladin and got to 50ish. Then I quit playing WoW until just recently with the newest Expansion. Any pointers on how to learn the new instances because it seems no one wants to invite someone that doesn't know the instance. Everytime, I try to get invited with my new character (neither paladin or hunter) I get kicked because I explain I just hit where I'm told and people don't seem to like that idea. Any pointers?
Can you folks help an instance noob out? What are your tips and tricks for convincing a group you've got the goods despite not having seen the inside of the dungeon?
