If you do #6, I think you can safely skip #1-5. Like @dgates01 said, it’s great that you’re being so careful with your ride, but three weeks isn’t really that long. Have your friend give it a good, long drive, and don’t worry about the rest. If you’re concerned about mice, have your friend pop the hood and look for signs of nesting. They’re more likely to attack the electrical wires than other parts of the car. The car cover is optional - I’d say just put a good coat of wax on it (it’s a lot to ask your friend to uncover and cover it, plus driving it too).

thanks @WiiMaster @dgates01 @DerekWildstar for your swift responses.
I asked my friend to drive it, but he couldn't promise as he might come up with plans to go out of town as well. Do you think i should still not do anything? No worries if it's not driven?

I really wouldn't worry about it. Worst case scenario, you need a jump start or you need to put some air in your tires. Neither of which are worth losing sleep over. Enjoy your trip! Going anywhere special?
