#middle-column {
width:750px !important;
}

will set this width, but doing so will essentially fix the width of all layout table pages.

This may prove to be a long road your heading down.

185 and 175 are narrow for a Moodle theme. However, assuming you are working in a very controlled environment (i.e. users won't be able to add their own sideblocks once you get started), I can see the desire for the narrow widths.

The problem with your widths not taking effect might have something to do with a mixture between the browser you're using and the width of the content on the page.

As a test, change the config.php width items to something large - like 250px and see if that changes anything for you. If it works, then you'll know that the PHP is working.

Then, consider adding this to your stylesheet:

#left-column {
width:185px;
}

#right-column {
width:175px;
}

You might need to add !important to the widths, but this should lock things into place.

Can you tell us where the icons came from? Are they GPL? Did you create them? Or, are they licensed under some other creator?

Lastly, can others use them? If so, under what context?

This code is redundant. This should work just fine:

#inst92.sideblock .title h2 {
font-size:13px;
font-weight:bold;
color:#000000;
}

I personally don't think that this added functionality in one non-compliant web browser is worth breaking standards of accessibility.
