Congrats on your first Ball! Trust me, it won't be your last.
It sounds like you're good to go for your enclosure, but as for handling, leave him/her alone for a week (like you know) and then after that handle him/her for only 10-15 minutes every other day for the next few weeks. That way, you don't stress her out too much in the beginning. After that you should have a good feel for his/her personality (ie. if she's skittish, adventurous, nippy, etc.) and that'll tell you more about how to handle.
Also, I'd wait 48 hours after feeding before you handle him/her, it gives more time to fully digest.![]()
