Q9. Speak to the capt and suggest he/she calls in sick. If he insists on flying say that you will call in sick yourself.
Q10. Mention the words "I DO NOT FEEL COMFORTABLE with that". If he still insists then repeat your feelings. If he still insists and tells you it will be OK I've done it before then you have no choice but to tell him he has put you in an awkward situation and if he continues you will take control. Stick to the SOP's, report him if you have to as he may well do it again.
