I think this is my 5th Presidential election. What you need to do is list the issues that are important to you. Then you need to see which candidate is the closest to your beliefs. I think it is important to listen to the spin but listen to both sides. For one, it makes it fun. For the most part politics are boring but watching the spin doctors duke it out is good TV. You're not going to find a true fair and balanced source so don't waste your time. Just take it all in and digest it and then make a decision.
I think the first time I voted I just voted for who my parents liked. Looking back I think that was a mistake. It turned out it didn't end up mattering but I think it is important, especially now to cast a good vote. But don't worry too much about it unless you're in one of the swing states because if you're not, then you vote doesn't really count.
