Having a couple issues with CSS and VisualForce datatable formatting. 

I am rendering a visual force page using a seperate page with renderAs="pdf". This just makes it easier to maintain just what I need to display. The visualForce page saves as a pdf attachment on the main account record. However when I view the stored PDF the datatable formatting is not displaying as it is on the main VF page.

How can I maintain the solid border and font colors on the rendered pdf ? 
Also, how can I control the cell padding using CSS instead of using the cellpadding parameter on the datatable tag. Is there a way to automaically scale the data table width should a table be long ? 

Main Visual Formce Page - PROD_UW_AccountSummary

<apex:page standardStylesheets="true"  standardController="Account_Summary__c" readOnly="false" extensions="AccountSummaryController"  >
<apex:stylesheet value="{!URLFOR($Resource.pdfcssresource, 'CREresource_CRE.css')}"/>
......
 <apex:pageBlockSection columns="1" id="section2b" title="* Expiring Excess of Loss Contract Information" showHeader="true"  >  
    <apex:outputPanel id="out2b" >
       <apex:actionstatus startText="loading...">
           <apex:facet name="stop" >
              <apex:outputPanel >
                  <apex:dataTable styleClass="alldatatables" value="{!contractSectionList}" var="cs" cellpadding="5" rowClasses="alldatarows"  >
                       <apex:column value="{!cs.MR_Contract__c}" headerValue="Contract"  />
                       <apex:column value="{!cs.Name}" headerValue="Section"/>
