Ask HN: Form letter for getting info as shareholder of a private company?

I have shares in a private California tech company that I used to work for. They have become very profitable and I want to make sure I'm not going to get screwed by holding onto the shares. They are offering to buy back the shares at the current 409a valuation, which has increased >10x since I exercised my options.

Does anybody have a form letter for requesting legally entitled information? I'm thinking cap table, bylaws, financials. Am I missing anything?
