Is there such thing as a JSF Init Page Load? the same thing that .net has with Page_Load? How do i init the code behind bean?

I had the same problem. What you can do is the following:
in your Bean you need all your request parameters as properties with getter and setter.
additionally add a boolan prepare property. Set this to false at the beans constructor : this.prepare = false;
in your faces config define your bean this way :
<managed-bean>
        <managed-bean-name>myBean</managed-bean-name>
        <managed-bean-class>org.you.package.beans.myBean</managed-bean-class>
        <managed-bean-scope>request</managed-bean-scope>
        <managed-property>
             <property-name>requestParam01</property-name>
             <value>#{param.requestParam01}</value>
         </managed-property>
         <managed-property>
             <property-name>requestParam02</property-name>
             <value>#{param.requestParam02}</value>
         </managed-property>
         <managed-property>
             <property-name>prepare</property-name>
             <value>true</value>
         </managed-property>
    </managed-bean>in your view add such a single line at the beginning ( right under <f:view... > )
<h:panelGroup rendered="#{myBean.prepare}" />now, tomcat will execute myBean.getPrepare( )
this method should look like this :
public boolean getPrepare()
          if (prepare)
               //do what you want with your request params. they are already set at this point !
          prepare = false;
         return prepare;
     }after loading the view once, the getPrepare Method is executed and the prepare property is set to false.
I need that, because getPrepare is loaded at any ajax page reload, too. ( I'm using icefaces )
access your jsf page with : http:localhost:8080/whatever/myPage.iface?requestParam01=hello&requestParam02=World
