I'm trying to create a team site with some web part pages that will be used to
enhance the navigation around the site. My initial problem stems from the fact
that a new web part page doesn't have any of the left-hand navigation that the
site's default home page does. That seems to be easily fixed in SharePoint
Designer by finding the right cell on the LHS and picking "Default to Master's
Content".

That then causes the Site Content nav part to appear, but the width of that
column is less than the width of the same column on the home page. It looks as
if the width is being set in the master page but the home page is using the same
master page, so I am now stuck at trying to figure out how to get the appearance
of the web part page to be closer to that of the home page.

Can anyone point me in the direction of some tutorials, or explain to me what I
need to change, please?
