Data is a major problem with GIS, so you identified it.=20
But there is some free data around. Did you check the links from

Again you intuitively hit another big problem with GIS data.
Data exchange formats are a problem. There is no good standard.
And you need to do a lot of conversion. Most widely used formats are
proprietory or at least tightly controlled by GIS companies.
A lot of people had the idea to utilise XML to define new formats.
I found this nice article which talks about the advantages (I guess it
was written last year)
I am not aware of widely used DTDs.
GeoVRML at least is an SGML application, but of course with a different
