Pligg Support

When I add a new page from the admin panel it doesn't dynamically add to the navigation bar. I've had to go into the header.tpl file to manually enter it.
Two issues I'm having:
1. Is there a way to use smarty code for the ahref to the page?
2. For the if statement to set the page to active I only have the option of $pagename eq "page" for it work with a custom page. However I have more than one custom page so they are all showing as active. Is there a different variable I could use? I try writing in the page name I've assigned but it doesn't work.
I'd like to use the voting system just for user submitted images. How can I get rid of the news article uploader have only an image uploader?
How can I replace the URL uploader for an image uploader?
Is there any way to disable the down vote? I want only the functionality to upvote a story
I'd like to remove the requirement to assign a category with a submission. I can't find the validation which is checking for this. Simply removing the field doesn't work.
Is there any way to change the text found in the cachec/c_____languages_lang_english_conf__.php file? I want to change 'PLIGG_Visual_What_Is_Pligg_Text' => 'Pligg is an open source content management system that lets you easily create your own user-powered website.',
