<DIV ID="d1" onmouseover="show(this,ds1);" class="menu">News</DIV>

What does it actually mean to send 'this' to the function Show ? Is it a
referanse to <div id="d1"... > tag ?

Could I swap 'this' with 'd1' and it would be just the same ?

Its a reference to the current element. Which is the same as
document.getElementById('d1').

No, 'd1' (and 'ds1') are a nasty non-standard thing with limited support.
Switch to the standard DOM.
