You need to install all the permanent fixes. The fixes that use the green font will work with your current campaign, the fixes with the blue font may work with your current campaign, the fixes with the red font will not work with your current campaign. It would be best to restart your current campaign unless you are very far into it, in which case you can continue at your own risk.
Temporary fixes are just that, temporary and should be used only to get around certain problems (which are detailed in the description for them). Optional fixes are if you wish to change or delete the client ruler portion of the script which in EB1.1 can cause a lot of CTDs. Once again they are colour-coded following the above green/red/blue scheme.
