Hide SUNY Libraries: to hide the list of libraries on the full record you can either add this code to your custom.css: /**Hide Other Libraries **/ prm-alma-other-members { display: none;}
or you can uncheck "Display locations from member institutions" in the view configuration on the general page, under Discovery Network Settings. It can take a day or two for this change to populate.
I don't know how either of these changes will affect advanced search or facets but feel free to poke around and post your findings here.
Modify style of locations and call number: I couldn't find information about applying style to pieces of the calculated availability. You could try playing with the code that can be used to add content to the calculated availability (add "Call Number"): /* call number hack */
