Restrict access to reports and right click menu

I have ben trying to make a role for some "asset managers" in my org that only need to be able to view asset data and modify the comments and barcode fields for an asset.  I only want them to be able to see a folder of reports and not all of them and I want to be able to take resource manager off of the right-click menu.  So far I have been able to restrict them to edit just the barcode and comments sections.  I am having trouble getting just the reports I want displayed for them and remove access to resource manage. 

I know these can be a pain... Any suggestions?
