Hi, Smithie! Your best bet will be to spend a good long time reading posts here...tons of great info! Also consider purchasing a book on greys - there are lots out there & come in handy.
The biggest piece of advice I would give would be to practice a lot of patience with your new bird. They live a long time, so for them to take a month getting used to something is really not a long time at all. Be quiet and gentle with your bird. When looking at him, look at him sideways, narrow your eyes and lower your head a little. This makes you appear friendly. When approaching with your hands, come in from the side/back (a front/top approach can seem threatening). Those are the best tips I've picked up and they all work for me.
Best of luck to you ... we look forward to hearing all about it!
