on the max samples I've got 15000, is that to high? also on max time I have it to 0 so it would render till complete, it think that was a mistake....LOL

A render stops when one of the end conditions is met. I routinely have convergence set to 95%, iterations set to 50,000, and time set to 30 hours.

Now if the render stops and you don't think it ran long enough pop out the left side panel and increase your iterations, and/or time, then hit continue and your render will resume. If you have draw dome turned on, then you can also adjust the tone mapping, even after the render is complete, without having to rerun the render.
