Tara, you've mentioned moving out from the group home and that is a huge step to take. I have found a website with a checklist on moving out for the first time on your own. Sometimes it is a good idea to plan things out and write them down before stepping into them. Good Luck!
Following a car, my next big "adult" goal is to be able to move out of my parents house and have my own apartment. I realize this may take some time but it will be one of the next things I start working towards after I am able to purchase a car.
