Resolve conflict between two Magento extensions

Should be a simple project for a Magento expert. I have a custom extension that works fine and want to use this extension as well [login to view URL] , but there is some kind of conflict, possibly javascript related. I just need both extension to work. Only [login to view URL] is the only file where the issue occurs. Also, another extension is not working properly and should be an easy fix, [login to view URL] this shows the full path to a product, but on the product page 'Home' is replaced with the name of the root category and the wrong link. I would like to get these resolved asap. You would get access to my development site to implement the fix and then send me details so I could copy it over to the live site. Please read the project first and write the word "Understood". Also write your steps and suggestions to complete the project with a short description of what you understood.
