Q&A plugin customization and pages

Hi, hopefully I am asking this correctly. I am using the Q&A plug in and I wanted to add some text at the top of the questions page and also customize the side bars (currently it shows my blog sidebar but I don’t know how that was set up), but I am not sure where the pages are that contain the question information . This may be a super simple answer but for some reason I cannot seem to figure it out. Thank you so much for your help.
