The above post is definitely the way to go if you want the redirect for form submission to redirect back to the original page the form was submitted on (thanks btw, it helped alot).
I also found a little more indepth explanation here:
I can explain what I did to help out others a bit.
Here are the added / edited files:
class MyModules_Contacts_IndexController extends Mage_Contacts_IndexController
protected function _redirect($path, $arguments = array())
For MyModules_All.xml (or whatever file you have that stores the list of your active modules, you could also create a seperate one per module)
<?xml version="1.0" encoding="utf-8"?>
That is it. Upload those and you are good to go. Make sure to flush your cache after uploading those!
Now, you *may* lose the notification that it was successfully submitted.
I was already overriding the original form layout (app/design/frontend/base/default/template/contacts/form.phtml) so I just needed to change:
<div id="messages_product_view"><?php echo $this->getMessagesBlock()->getGroupedHtml() ?></div>
<div id="messages_product_view"><?php Mage::app()->getLayout()->getMessagesBlock()->setMessages(Mage::getSingleton('customer/session')->getMessages(true)); ?></div>
