Client Tracking System -- coding changes to application

I have a list of changes I wish to have done to my current application -- it is coded in PHP with MySQL backend on a CentOS server running cPanel. It works very well.. these are not bug fixes but rather upgrades. I have attached a doc listing the changes - if there are questions on any of the tasks please PM me. I have attached some screenshots so you can get an idea of how the app looks and works.. it is very simple design - no graphics. Lastly, beside changes - I would like simple way to install app - I am Linux user not admin - so it can involve some minor command line requirements.
