That's okay, you have to set the checkboxes with:
   legend.changeNodeStatus("roads", "on");

nor do they change anything if I check/uncheck them and

That's not okay.

 The image that dislpays the color and shape of the layers

I assume that's in your window.onload function. And I am guessing that
when you say the alert doesn't give any errors, the alert isn't
opening at all. So I don't think your window.onload is getting called,
or it is generating an error before legend_xml gets initialized.

Try moving your alert up earlier in the code to see where it's
crapping out. Like to the first line in window.onload() so you can see
if window.onload is even getting called.
