@NitinDhanrajani, as a risk management tool it is recommended to book partial profits when 50-60 % of the target is achieved. For eg in our case we sold at 82 and booked profits when the price was around 30 (we booked completely in this case) which is kind of 65% of the fall.
Answering your 2nd question, if Nifty closes any where above 9000 on 07May, then you don't have buy back. It expires worthless at 0 and you save on your brokerage.
Also it is necessary to buy back put if it is above 9000 on 7th May expiry
