When positioning empty in my company, we always bring a minimum of 25 tonnes of fuel. Maximum de-rate+assumed temperature for takeoff and de-rated climb. Depending on your rotation speed, you might end up on a initial climb speed slightly higher than normal V2+10/25, but dont worry to much about that. Don't start flaps retraction until acceleration height even if slightly above the flaps 10-"bug". When accelerating, keep the necessary pitch and do not delay retracting flaps passing through the recommended speed for the next position. Exceeding structural speeds should not be a problem in neither VNAV nor FLCH.
Things happens very quickly during these takeoffs. It's usually easier if you do a noise abatement procedure. I suggest selecting 3000ft for acceleration height and 1500 for thrust reduction.
Good luck!
