Why should i include the ModuleID when developing a custom module & table schema? What is the benefit of including this value and are there other values to be included as well? Thanks!!

This really depends on what types of information you are storing, and the desired way that it is associated. For example, take my guestbook module, each entry is tied to a specific module instance, thus ModuleId is used. I then can make a foreign key to the modules table, with ON DELETE CASCADE set and if the module is deleted I will get an auto cleanup of that data. Now, in other modules you might have information that is stored on a site basis, for those you would use the PortalId as a key. The true question is how should data be stored in relation to multiple instances of a module in a single DNN portal or DNN installation.
