Member levels & configuration

Not sure if I’m missing something here, but I’m trying to enable membership levels the ability to submit posts, as well as edit them and see a list of their posts and status with out having to enter through the backend. Is there a way to customize the toolbar or add short codes to pages.

My issue with the toolbar: When just using s2member capabilities the toolbar only gives level 0 members the option to add/edit their events (not posts). When I update the capabilities using the user role editor and I click “edit posts” the tool bar changes and the user can see practically everything in the drop down menu and gives them the option to click on pages, settings, toolbox, ifeature pro, design approval system. How can I work around this and enable my users an easy way to edit posts (and only posts) through the front end??

I am not a coder/developer so please speak in lay terms.

Thank you in advance!
