I have an immensely complicated VF page, with some special behavior in one section.  To get the special behavior to work, I had to litter the layout with outputpanels and actionregions (thanks to Henk Henk for his help with that).  Now it behaves correctly, but the active section has crap formatting - captions won't right justify, data fields won't line up with the rest of the form.

I've tried class and styleclass and labelstyleclass and datastyleclass and inserting spans and divs and ths - nothing will fix the formatting.  I don't dare touch the outputpanels themselves because the behavior will stop working.  Here's a portion of the page:

<apex:page showHeader="true" sidebar="true" standardController="TrialSubscription__c" extensions="NewWithTrial">
    <apex:form id="TheForm">
        <apex:actionFunction name="ChangeCloud" action="{!changeCloud}" rerender="CloudSection" status="cloudChangeStatus" />
        <apex:actionFunction name="ChangeProduct" action="{!changeProduct}" rerender="ProductSection, ConferencingSection, StorageSection, CallingSection" status="productChangeStatus" />
        <apex:actionFunction name="ChangeCalling" action="{!changeCalling}" rerender="CallingSection" status="callingChangeStatus" />
        <apex:actionfunction name="ChangeGenerate" action="{!changeGenerate}" rerender="ForcePasswordChange, EnterPassword" status="generateChangeStatus" />
        <apex:pageBlock mode="edit">
            <apex:pageBlockSection columns="2" title="Lead Information">
                <apex:inputField value="{!theLead.FirstName}" required="true" />
                <apex:inputField value="{!theLead.Phone}" required="true" />
                <apex:inputField value="{!theLead.LastName}" required="true" />

                        </apex:pageblocksectionitem>
                    </apex:outputpanel>

                        <apex:outputpanel id="renderPasswordField" rendered="{!NOT(generatePassword)}" >

                                <apex:inputsecret id="password" value="{!password}" styleclass="dataCol last" />
                            </apex:pageblocksectionitem>
                        </apex:outputpanel>
                    </apex:outputpanel>
                    <apex:actionstatus id="generateChangeStatus" starttext="Changing security options..." stoptext="" />
                </apex:pageblocksection>
            </apex:actionregion>
            <apex:pageBlockButtons location="bottom">
                <apex:commandButton value="Create" action="{!save}"/>
                <apex:commandButton value="Cancel" action="{!cancel}"/>
            </apex:pageBlockButtons>
        </apex:pageBlock>
        <apex:pagemessages ></apex:pagemessages>
    </apex:form>
</apex:page>

Here's the special behavior function from the controller:

    public PageReference changeGenerate() {
        forceChangePassword = generatePassword;
        return null;
    }

With these tags in it, it finally used the right font, but the labels and fields are still not lined up with the rest of the form, and I've run out of things to try.  Any ideas?
