When you add the URI to that Doctype the browser you are testing in 
switches to "Standards mode, stops emulating bugs in earlier versions 
of that browser, and pays more attention to the standards (e.g. 
ignoring lengths lacking units).

Both are correct. The latter is more useful as it doesn't require any 
SGML parser to recognize the public identifier.

They both point to the same file.

There are over a dozen ISO character sets. The Euro sign appears is 
iso-8859-15.

The correct place to set it is the http headers the server sends before 
the document (and those headers should represent the character encoding 
you saved the document in, not a random character encoding which 
happens to have the characters you are using in it). This should be 
explained (with lots of links) by any error message the validator 
produces in relation to character sets.

Not setting it is more likely to cause such problems. Their browsers 
will have to use their default character encoding.
