In the help files (Help -> Reference Guide -> Standard TeXmacs styles, 
at par 4.1.2.) you will find a general description of the mechanism for 
rendering titles.

As far as I understand the key macro that lays out the title, 
doc-data-main, is not implemented as a TeXmacs macro but as a Scheme 
function (here the help document might be inaccurate in suggesting that 
it is a TeXmacs macro); you can find it in 
$TEXMACS_PATH/progs/database/title-markup.scm, and I copy it here

(tm-define (doc-data-main t)
  `(document
     ,@(select t '(doc-title))
     ,@(select t '(doc-subtitle))
     ,@(with authors (select t '(doc-author))
         (if (<= (length authors) 1) authors
             (list `(doc-authors ,@authors))))
     ,@(select t '(doc-date))
     ,@(select t '(doc-misc))
     ,@(select t '(doc-inactive))))

You can place your new definition in a Scheme module that you load from 
your document (please ask if you do not know how to do that).

Rearranging the order of the elements is intuitive I think. Here is an 
example, where I place the author first and set a line between author 
and title (I tested it and it works):

(tm-define (doc-data-main t)
  `(document
     ,@(with authors (select t '(doc-author))
         (if (<= (length authors) 1) authors
             (list `(doc-authors ,@authors))))
     (line (point "0par" "0") (point "1par" "0"))
     ,@(select t '(doc-title))
     ,@(select t '(doc-subtitle))
     ,@(select t '(doc-date))
     ,@(select t '(doc-misc))
     ,@(select t '(doc-inactive))))

Said this, what I wrote is not authoritative at all :-) The mechanism 
for the layout is complex and there are many parts which I haven't grasped.

I hope that someone else can extend/complete/correct what I wrote, and 
that it helps to get you started.

I would say that for further info either ask here again, or if the 
discussion becomes quite complex maybe the forum at 
http://forum.texmacs.cn/ might be a good place.
