Can you download free open source media centre software XBMC using Debian Linux
Yes, you can. I personally suggest OpenElec because it is all I have ever used, but there are about 3 or 4 xbmc focused distros for the RPi at this time.
There is a media center sub-forum on these forums, you will probably find some more informed opinions there as well.
