I'd wait a bit longer for him to get used to his new envirionment before strting to work with him. Maybe a week or two. Sitting by the cage and talking sofly is a great way to start. You can also offer bird safe treats through the cage bars to get him used to your fingers and not be scared of them. The stick method will work, but for me I like to get right in there and show 1. I'm not affraid and 2. I'm the top bird.
Make sure his wing feathers are clipped as that will keep him in line. Also if he is not already on a pellet diet get him on those once he has completely settled. Make sure he gets lots of freash foods too. Veggies, fruit, pasta, rice and some nuts.
Also if in doubt ask us lots of questions, and remember there are no dumb questions.
