It is not only a modeline format, it also uses gnus buffers
configuration (look at the docstring of gnus-buffer-configuration)

For example I use the following to have the frame splitted horizontally
while reading a message with the message body at the bottom and the
group summary on the top :

    (gnus-add-configuration
     '(article
       (vertical 1.0 (summary 13 point)
                 (article 1.0) )))

> 2. abbreviated date (i.e. "Mo 13")

With a custom date format :
;; affichage de la date en relatif
(setq gnus-user-date-format-alist
          '(((gnus-seconds-today) . "     %k:%M")                               
;dans la journée =      14:39
                ((+ 86400 (gnus-seconds-today)) . "hier %k:%M")     ;hier       
     = hier 14:39
                ((+ 604800 (gnus-seconds-today)) . "%a  %k:%M")     ;dans la 
semaine = sam  14:39
                ((gnus-seconds-month) . "%a  %d")                               
;ce mois         = sam  28
                ((gnus-seconds-year) . "%b %d")                                 
;durant l'année  = mai  28
                (t . "%b %d '%y")))                                             
;le reste        = mai  28 '05

The formats are those of format-time-string and should use your locals
to write the days and months names in your language.

> 3. very nice threading format

You need to set the use of the thread display in the mode line format,
for example :
(setq gnus-summary-line-format 
      (concat
       "%*%5{%U%R%z%}"
       "%4{|%}"
       "%2{%-10&user-date;%}"
       "%4{|%}"
       "%2{ %}%(%-24,24f"
       "%4{|%}"
       "%2{%5i%}"
       "%4{|%}"
       "%2{%6k %}%)"
       "%4{|%}"
       "%2{ %}%3{%B%}%1{%s%}\n")) ;%B = threads display

The threads nice characters can be obtained by changing the default
display; It works nice under GNU/Linux and OSX (with atsui support), I
have not tested recently with Windows.

          (setq gnus-sum-thread-tree-root "\x490b3 ") ; "> "
          (setq gnus-sum-thread-tree-false-root "\x490b3 ")                    
; "> "
          (setq gnus-sum-thread-tree-single-indent "  ")                 ; ""
          (setq gnus-sum-thread-tree-leaf-with-other "\x4903c\x49020\x490fb ") 
; "+-> "
          (setq gnus-sum-thread-tree-vertical "\x49022")                       
; "| "
          (setq gnus-sum-thread-tree-single-leaf "\x49034\x49020\x490fb ")      
; "\\-> "

Some variants :
          (setq gnus-sum-thread-tree-root "\x4912f ")                          
; "> "
          (setq gnus-sum-thread-tree-false-root "\x490f8 ")                    
; "> "
          (setq gnus-sum-thread-tree-false-root "\x4912f ")                    
; "> "
          (setq gnus-sum-thread-tree-single-indent "\x4912e ")                 
; ""
          (setq gnus-sum-thread-tree-single-indent "\x490b3 ")                 
; ""
          (setq gnus-sum-thread-tree-single-leaf "\x490b0\x49020\x490fa ")   ; 
"\\-> "

> Any ideas?

Let's try what I wrote and look at the docstrings of the different
variables and function to know the format specifiers to be able to build
your own display.
