2. For the default spacing that LyX/Latex uses for the following 
(assuming article class):
    - above a section heading, subsection heading or abstract heading,
    - between any of these headings and the text corresponding to the 
section/subsection/abstract,
I see entries (in article.cls) such as: 
[EMAIL PROTECTED] [EMAIL PROTECTED]
                                   {-3.5ex [EMAIL PROTECTED] -1ex [EMAIL PROTECTED] -.2ex}%
                                   {2.3ex [EMAIL PROTECTED]
                                   {\normalfont\Large\bfseries}}
... what do the various ex spacings in this command correspond to? I 
assume that if I know the answer to 1 and the current question, I should 
be able to renewcommand any section/subsection I want and specify the 
appropriate spacing I need...
e.g.

\makeatletter
\newlength{\mySpaceUnder}
\newlength{\mySpaceOver}
\setlength{\mySpaceUnder}{4cm plus .2ex}  % 4cm as an example ;-)
\setlength{\mySpaceOver}{3cm plus -1ex minus-.2ex}   % 3cm as an example
[EMAIL PROTECTED] [EMAIL PROTECTED]
                                   {\mySpaceOver}%
                                   {\mySpaceUnder}%
                                   {\normalfont\Large\bfseries}}
\makeatother
[EMAIL PROTECTED] is called with
#1: the name
#2: internal number
#3: current font size
#4: space before
#5: space after
#6: commands befoer title
