The adult stuff, I think you have to setup another Boxee login as I believe your sources are stored under that and under that login you will want to turn adult stuff off and put a password on it (http://boxee.zendesk.com/entries/323080-settings-adult). Only add the sources with non adult stuff in under the new login and I would also make sure you password protect the adult share so that cannot be browsed in files menu.
Regarding NFOs ... I think you will be a really good test case for the Boxee documentation ... read this and see if it helps... and let us know where bits are confusing or don't make sense.
Be aware the boxee obviously has a browser so that bit is harder to control adult content wise. Unless you have a router side website filter.
I know there have been a few comments on the forum about the adult settings so have a search and they might help you or make you not want to leave the room when your kids are using it!!!
EDIT - OH and welcome to the forum ... its an awesome little box even if it does have a few little issues at the moment... enjoy!
