Joomla front-end PCP and Contribution Page Issues

1. If you try to visit a Personal Campaign Page that is in Approved status, you should get redirected to parent contribution page w/ message: "The Personal Campaign Page you have just visited is currently Not Approved. However you can still support the campaign by making a contribution here."

Using this URL for my PCP in front-end:
http://<my domain>/joomla159/index.php?option=com_civicrm&task=civicrm/contribute/pcp/info&id=1&reset=1

In Joomla front-end, the redirect doesn't work. Instead, you see the above status message displayed on the contribution page AFTER you then click the "Donate" button on the PCP.----

2. If admin enables an Honor Block for contribution page and doesn't put text in the optional honor_block_text field, you get a notice in Joomla:

Notice: Undefined index: honor_block_text in /Users/dgg/htdocs/joomla159/administrator/components/com_civicrm/civicrm/CRM/Contribute/Form/Contribution/Main.php on line 439

3. Get this notice on Thank-you Page - I filled in Honoree First and Last name (no prefix selected which is I think where this error is coming from. Probably need to to CRM_Utils_Array::value on all assigns in this section.

Notice: Undefined index: in /Users/dgg/htdocs/joomla159/administrator/components/com_civicrm/civicrm/CRM/Contribute/Form/Contribution/ThankYou.php on line 111
