First: I am a first time speaker at a convention (to happen in 2 days time) and I have no experience at all but I believe I can do so can anyone give me tips on how to look confident, engage the audience, inspire them and NOT SUCK...?

Practice your talk, out loud, at the speed you will be delivering it (which should be slower than you normally speak) as many times as possible. After the first few runthroughs, think about ways in which you can improve the talk—things you could communicate more clearly, slides that could be better presented, changes to the order that might help. Then make sure you practice the final version, out loud, at least three times in the exact form you intend to deliver it.
