I would start out slower. The biggest mistake that someone new to DOE can make is to jump into a large DOE.

Start out with a two level half - fractional factorial to determine which factors are significant. Run a few center points to detect whether curvature might be important.

After running and analyzing this screening experiment, you may run a modeling or optimizing experiment on the reduced number of factors.
