Congratulations on your new baby!!! How exciting!!!!!
The EASY method would support you nursing every two hours to four hours. The other nursing schedule you mentioned sounds more like nursing on demand. It is your choice what you want to do. I would opt for the every two hours to four hours. This ensures your baby is taking a big feed and filling his belly. If you listen to the swallowing of your little boy you will hear his pattern and hopefully be able to tell when he is full. Just listen and you will learn it I imagine.
About the throwing up, it is quite common for some babies and there is nothing medically wrong, for other babies, there is something wrong. Most common, I believe, would be reflux. There is a section on this website dedicated to it. I think other symptoms are that the baby doesn't like being on their back, that they cry after a feed, etc. I am not saying this is what your little one has, I'm just saying that you should be aware of what babies can suffer from.
By the way, you will receive much advice now that you are a mom. Take what you want and throw away the rest. This site is really helpful for figuring out what will work best for your little one.
I would suggest reading Tracy Hogg's book the Baby Whisperer, she really helps you learn to understand your little one.
Good luck
