G'day dee1984! It sounds as if you're off to a good start with your bird and it's great to see you asking questions. There's lots of experienced people here to help.
My birds were a bit beaky when they first arrived, so I searched all over YouTube for videos to help me stop the biting behaviour. If you type in 'stop a bird biting' or 'taming an aggressive bird', you'll come up with lots of ideas to show you how to train your bird.
Here's a few things I've learned.
Don't start an argument you can't win. If you ask the bird to step up and he doesn't want to, chasing him around and trying to force him to step up will only result in you getting bitten. It's the bird's only defence and he'll use it if you corner him. If he refuses to step up, wait a minute or two and try again. Or leave it for half an hour. Or,try using a stick for him to step onto - he may be afraid of hands.
When you offer your hand to a bitey or strange bird, always offer the back of your tightly stretched closed fist. That way, they can't get hold of your skin and it's harder for them to bite you. If you're clever, you can learn to turn your hand this way and that so that you never have to 'back down' from a bite. This is handy when you're trying to remove your bird from chomping on something you treasure!
Use bribery! I've used treats to coax my birds onto my hands and then more treats to keep them there. If they bite, I put them back on their perch. (NB. They really don't bite any more - just occasionally when they forget themselves). I've also used treats to teach recall and that's the most important lesson your bird will ever learn! My pair is fully flighted and they will fly to me from wherever when I call them. Mostly. Usually. Well, pretty often. It's a work in progress.
Someone once told me that a bird can't bite you if its mouth is full. So, you can offer a chopstick or pencil or stick for the bird to chomp on while you step him up or do whatever it is you need to do. Theoretically, while the bird's chewing on the stick, he's not chewing on you.
Lots of members like to use touch training and clicker training with their birds. (I haven't - simply because my guys began responding to simple 'good boy' and a treat - it's been easy for me, luckily). These methods have been proven to work with most birds, even aggressive ones. Again, search on YouTube for helpful videos - there's heaps of 'em.
Hope some of this helps? Please never hesitate to ask questions (we have a section called 'Questions and Answers' especially for that) and if you don't get a timely answer, then ask it again! Sometimes, people are sleeping, or bathing or at work or just in a coma. Answers will come eventually!
