Each article is written by a different author and I currently provide a Word template so they can see how their article will eventually look and how long it is, etc. I want to do the same for the ConTeXt version so I have created a template tex file they can simply \input at the top of their article. Processing the single article gives the desired output. So far so good.

Your simple version sets the bodyfont before \starttext

%%%% begin example
\setupbodyfont[termes,14pt]

\starttext

{\bfc Cheesy double boxed title}

\stoptext
%%%% end example

while your complexer version loads the bodyfont after \starttext 
(\startcomponent acts here as \starttext)

%%%% begin example
\starttext

\setupbodyfont[termes,14pt]

{\bfc Cheesy double boxed title}

\stoptext
%%%% end example

When you use a non standard font size (e.g. 14pt) size switches are 
sometimes ignored even with ConTeXt's fallback mechanism.

To get the correct size for the header you can either use a standard 
font size (14.4pt) or you add the following line before you set the 
global font for your document (ConTeXt does this by itself in most cases 
but it can fail).

     \definebodyfontenvironment [14pt]

I attached a slightly modified version of your project structure to show 
a different way to organize documents. What I would change is to use a 
better section name for each article, e.g. \Article (or \startArticle) 
is better than \MyTitle as first level header in each article.
