Need SEO by Yoast Plugin to work with Simple Press Forum. Plus 'add topic' button not working

Closed - This job posting has been filled and work has been completed.

Job Description

1). I need to have SEO by Yoast disabled for Simple Press Forum pages, so that the meta titles on pages such as http://www.usedbooksearch.net/forum/rare-books-forum/ have the forum topic title in them.
I have the same problem as this:
http://wordpress.org/support/topic/plugin-wordpress-seo-by-yoast-turn-off-yoast-wordpress-seo-for-simplepress

However, when I try and rewrite the title function in the header.php and functions.php file, the issue isn't resolved

(I have tried this: http://dottech.org/101602/how-to-make-yoast-wordpress-seo-work-with-simplepress-page-title-and-canonical-guide/)

2. The 'Add topic' button on my forum posts is returning 'javascript void' E.g. on http://www.usedbooksearch.net/forum/writers-forum/
I need this issue resolved

Many thanks
