On Q1, you have to qualify the answer a bit. Are the presentations available GIPS compliant or no? If you have 10 years or more  at least of compliant history , they have to show 10 years.
Again on Q2 , ditto. If less compliant is available then as many compliant years as available . Once compliant , they cannot uncompliant themselves. But once they started getting compliant they cannot then show less than since-inception-and-also-compliant history.
On Q3 , certainly , if they became compliant only in 2006 , then show 2007-‘11
Gross preferred but net   accepted. Disclose which one.
Q4 , the answer is obvious , why else would you take the risk of writing an option ? To cover some of the loss on your underlying position
