Seems like you're starting out in the best way Fg, lots of people get the snake and then start the questions - not a good beginning for snake or keeper... There are lots of experienced people here who can help you with everything you need to know, and there are a number of inexperienced members who jump in with bad advice too - had a snake for 3 months and think they know it all. I would suggest you establish a relationship with only a couple of experienced people, and stick with the advice they give you, or you'll end up with so many conflicting ideas and just become confused.
Bredli is a good first choice if you have the space to maintain them when they're adult size. The tendency to bite as a youngster has little to do with the way they were handled or the frequency of handling by the breeder, it's very much a characteristic of the individual animal at that stage in their life, and something you'll get used to in a short time. Some are bitey, some not. For a tiny, vulnerable python, the best approach is to bite first and ask questions later, or you'll be eaten! As most Morelia grow, they become less snappy and more confident - in my experience Bredli are very pleasant and very beautiful animals as adults.
Your interest in keeping it in your room is fine - your activities won't distract it at all.
