For question 2:
Possibly you can adapt the CSS file of your layout. Somwhere there is the definition for headlines (h1 ... h5). There you coud adapt the font variant by something similar to
font:small-caps 110% Verdana;.
Tip:
I'm using basically the arctic template. Within the file design.css you will find a headline section.
If small-caps should be used only for h1 then search for
/* special headlines */
and add the font variant as follows:
div.dokuwiki h1 {font-size: 160%; margin-left: 0px; font-weight: bold
; font-variant: small-caps}
If small caps should be used for all headline it is better to adapt the
/* general headline setup */.
Simply insert
font-variant: small-caps; into the div.
