Answer

You may use the layout 'A4' throughout (the one with two columns). For a block to span both columns you have to add

    span="all"

to the formatting objects. See http://cnx.org/content/m43650/latest/. This works fine with your example.

<fo:page-sequence master-reference="A4"> 
  <fo:flow flow-name="xsl-region-body">
   <fo:wrapper  font-family="Times" font-size="12pt" text-align="justify">
   <fo:block id="sec0"
             text-align="center"
             font-family="Helvetica"
             font-weight="bold"
             font-size="18pt"
             color="#0050B2" space-after.optimum="6pt"
             span="all">

   </fo:block>

   <fo:block space-after.optimum="6pt" span="all">
     When building PDF files, FOP normally supports only the base 14 font
     package defined in the Adobe PDF specification. That includes the
     following fonts: Helvetica, Times, Courier, Symbol and ZapfDingbats.
   </fo:block>

   <fo:block space-after.optimum="6pt" span="all">
     Font support in FOP can be extended by the addition of font metric
     files (written in XML) created from Adobe Type 1 fonts and Truetype
     fonts. No other font types (Type 3, etc.) are supported at this time.
   </fo:block>

   <fo:block id="sec1"
             font-family="Helvetica"
             font-weight="bold"

             color="#0050B2"

             space-before.optimum="12pt">

   </fo:block>

   <fo:block space-after.optimum="6pt" >
     As mentioned above you need an XML file containing font metrics to
     be able to use an additional font. FOP contains a tool that can generate
     such a font metrics file from a PFM file, which normally comes with the
     font file.

Question 2

I want column-count="2" to have only in some part of the page.

     FontBBox and Italic Angle can be found in the human-readable part of the PFB file.
     The PFMReader tool does not yet interpret PFB files, so if you want to be correct,
     you may have to adjust the values in the XML file manually. The constructed values
     however appear to have no visible influence.
