Do as they say. Integrate $I_n$ by parts, integrating the $x^n$ factor and differentiating the $e^{-2x^4}$ factor.

3. Right, a did that and I got p=32. Can someone check if this is correct?

I had p=8 when I did it this morning. I don't have time to re-check it now because I'm about to go out for the evening. Maybe someone else can adjudicate.

5. I got p=8 too.
