Question #1: For some reason, I can't seem to get my custom CSS file to be implemented into the theme. I've basically done this with the page.xml:
Before:
<action method="addItem"><type>skin_css</type><name>css/styles-ie.css</name><params/><if>lt IE 9</if></action>
<action method="addItem"><type>skin_css</type><name>css/styles-iefont.css</name><params/><if>gt IE 6</if></action>
<action method="addCss"><stylesheet>css/widgets.css</stylesheet></action>
<action method="addCss"><stylesheet>css/print.css</stylesheet><params>media="print"</params></action>
<action method="addItem"><type>js</type><name>lib/ds-sleight.js</name><params/><if>lt IE 7</if></action>
<action method="addItem"><type>skin_js</type><name>js/ie6.js</name><params/><if>lt IE 7</if></action>
After: (added inbetween)
<action method="addCss"><stylesheet>css/widgets.css</stylesheet></action>
<action method="addCss"><stylesheet>css/print.css</stylesheet><params>media="print"</params></action>
<action method="addCss"><stylesheet>css/hafner.css</stylesheet><params>media="screen"</params></action>
<action method="addItem"><type>skin_css</type><name>css/hafner.css</name></action>
<action method="addItem"><type>js</type><name>lib/ds-sleight.js</name><params/><if>lt IE 7</if></action>
<action method="addItem"><type>skin_js</type><name>js/ie6.js</name><params/><if>lt IE 7</if></action>
Am I missing something?
The code is in <block type="page/html_header" name="header" as="header">
