In reply to Professor Meow Meow:
Great name. I don't think it's possible to advise you on boots over the Internet, except to say try on as many as you can and buy the ones that fit. Good socks can help too.
As for tents, 3 kg sounds heavy to me, but it depends what else you are carrying and how you want to balance weight carried with tent preference. If you have decided not to share tents then why do you need a 2 man tent? Are you sharing cooking equipment? How far are you planning on going each day?
As a general rule you shouldn't aim to carry more than 1/4 of your weight, maybe a little more if you are fit and strong.
What was it you didn't like about the other tent?
