I'm graphing a quadratic equation, I have all my info put into the stat area and nothing in the Y= area. When I graph it the points are small boxes, there is no graph line and it won't allow me to do any 2nd Trace options

If you're doing a stat plot, you're plotting a discrete set of points. The calculator doesn't interpolate between the data points.
If you want to graph a quadratic equation, then do so. Enter it in as a Y= equation and plot it as such. This will not only connect the points (unless you tell it not to), but will also allow you to do things like trace.
