When I was 16 I took 30 credits a quarter and my math GPA suffered will this effect my ability to go to grad school? I took all my college level math courses when I was 16 in running start while taking 30 credits a quarter(don't ask me what was going through my head at the time). As you can imagine I got an average of about a 2.8, in most of these courses....However, when I went to a 4 year they restarted my GPA and I currently have a 3.67 and it has only been climbing the last few quarters. I am about to graduate and I would like to go to Grad school. I am an Information Systems Major e.g. business. Is it plausible to at least get into a decent business Phd program ?

I see that most schools seem to look at these grades in particular.
If you were officially a high school student at the time, then you may not need to submit those grades to the universities to which you apply for graduate admissions at all. In general, anything that is done before undergraduate is ignored in graduate admissions.

On the other hand, if the grades appear on your undergraduate transcript (because you applied to have the credits accepted towards graduation), then you will need to explain the situation, as keshlam suggests. Again, though, the fact that you were so young is a reasonable justification for your performance, so I wouldn't worry about it too much.
