That's pretty easy. You have to create a customization layer as shown in 
[1] and insert the following parameter:

 <xsl:param name="body.font.family">
   <xsl:choose>
     <xsl:when test="/book/@lang='ja'">
      <xsl:text><!-- Insert your fonts here --></xsl:text>
     </xsl:when>
     <xsl:otherwise>serif</xsl:otherwise>
   </xsl:choose>
 </xsl:param>

Probably you need to configure the other parameters like sans.font.family 
as well (see [2]).

For this check I need to know where your confidentiality element is 
allowed.

I am not 100% sure, maybe there are better methods, but you can change the 
attribute set chapter.titlepage.recto.style (untested):

 <xsl:attribute-set name="chapter.titlepage.recto.style">
   <xsl:attribute name="color">
     <xsl:choose>
       <!-- Adapt the XPath in test to your needs -->
       <xsl:when test="/*/confidentiality = 'Confidental'">
         <xsl:text>black</xsl:text>
       </xsl:when>
       <xsl:otherwise>blue</xsl:otherwise>
     </xsl:choose>
   </xsl:attribute>
 </xsl:attribute-set>

Insert it into your customization layer too. :)


Hope that helps,
Tom
