you can peek in cont-log.tex to see what logos are available as core 
functionality; also,

\usemodule[abr-01]  %  or -02

will give you a large collection of predefined ones. The advantage of that 
is that you can also ask for the list of used logos (and abbr).

cap will not work in headings (since the argumen tto cap is pretty 
complicated and will break), use \sc here (and when possible)

cap may become better in the future but tex itself has its limitations

\setuphead
   [section]
   [textstyle=\sc,
    before=\noindentation\hairline\blank,
    after={\nowhitespace\hairline\blank[line]}]

so, you should add \noindentation; but beware: your coding may end up in 
lone rules since a blank is a valid breakpoint (a herd \kern is probably 
better)

Now, it is often far better not to hook niceties into before and after 
since you want proper spacing. The next alternative is therefore better:

% let's demo framed texts:

\defineframed
   [ChapterText]
   [strut=no, % try yes with \showstruts
    width=broad,
    align=right,
    topframe=on,
    bottomframe=on,
    leftframe=off,
    rightframe=off,
    framecolor=darkred,
    rulethickness=1pt,
    offset=0pt]

% the dedicated section command

\def\MyTitle#1#2%
   {\ChapterText{\vskip1ex#1\quad#2\vskip1ex}}

\setuphead
   [section]
   [textstyle=\sc,
    color=red,
    before=\blank,
    after=\blank,
    command=\MyTitle]

\setuphead
   [chapter]
   [color=darkred]

As you can see here, i also set the color

color directives put nodes in the tex mvl list and these interfere with 
spacing; use the color=darkred instead

\definestartstop[IntroText][style=\sl]

\IntroText{The ....} is more abstract and permits changing fonts more easily
