Do I need to submit my studys actual materials in toto along with the application?
As long as the description you provide of your methods and materials is clear/comprehensive AND the topic of study is NOT a sensitive one (e.g., sex-related issues, illegal behaviours) AND you are NOT employing deception, then it isn’t necessary to provide copies of your research materials a priori (unless asked to do so by the ethics reviewer, who may not be familiar with a particular instrument). As implied then, if your study involves sensitive issues and/or deception, then you should submit the relevant materials without waiting to be asked (or it may hold up your application). If you are using a new (non-standard) instrument and/or your materials are difficult to describe within the confines of the application, you may find it easier to simply submit them at the time of application.
