If the dashboard has the marketplace then I cant see why not. However, a ban will be on your xbox if you may do so.
Unfortunately not. An Xbox LIVE account is required in order to purchase Dashboard Themes and much, much more.
I' m sorry but that's more of a opinion sort of answer it would be best to send a letter or email the the makers of the Xbox and see why you cant see your friends on the Xbox dashboard you should be able to get an answer from them.
At the dashboard click create an account!

Xbox Live originally debuted on the original Xbox. When you inserted the disc that came with the Xbox Live starter kit, it updated the dashboard to include Xbox Live. It was much different, however, than it is now. With Xbox 360, Xbox Live is integrated with the Dashboard. On the Xbox, it was mainly used for playing other people over the internet. There was not much in terms of downloadable games and video content. The Xbox Live service officially ended for Xbox on April 15, 2010
