I have to uncheck a selectBooleanCheckbox lower down in the form IF it
is checked.

So I added the showOnWebAjx id to the reRender shown below.

<h:selectOneMenu id="estatus" value="#{itemHome.instance.estatus}"
    required="true">
    <f:selectItems id="estatuses"
        value="#{mconsoleContext.ecometryItemStatusCodes}" />
    <a:support event="onchange"
        reRender="showOnWebAjx, ecycleWeeksAjx, orderSizeFoodPo=

Ajx,

upcAjx, kitAjx, preOrderAjx, priorityProcessingAjx"

actionListener="#{itemHome.resetPreOrderAndPriorityProcessingFlag}"
        ajaxSingle="true" />
</h:selectOneMenu>

I don't know how to uncheck the box but with the below code I can tell
when it is C1 or H1 (2 of the values where we want to uncheck the box,
the rest of the time we do nothing)

<s:decorate id="showOnWebFlagDecoration"
    template="/layout/edit.xhtml">
    <ui:define name="label">#{messages.showOnWebFlag}</ui:define>

<a:outputPanel id="showOnWebAjx">

<c:if test="#{'C1' eq itemHome.instance.estatus || 'H1' eq
itemHome.instance.estatus}">UNCHECK showOnWebFlag!!</c:if>

    <h:selectBooleanCheckbox id="showOnWebFlag"
        value="#{itemHome.instance.showOnWebFlag}"/>

</a:outputPanel>

</s:decorate>

The a:outputPanel and c:if test are my additions.

What is the proper / correct way to uncheck that box using JSF and/or
RichFaces?

Set the corresponding backing bean property to 'false'.
