How do I tell Finder to always show my Library folder on Mavericks? I thought there was a checkbox to suppress the hiding of my user Library folder on Mavericks, but I can't seem to find it. I appreciate hiding Library by default, but since Lion have missed it being easily accessible.

How can I get the library folder to be visible in Finder, the Finder go menus / file save dialogs without needing to hold down shift?
Open your desired user Home folder in Finder (ShiftCommand + H) and select View > Show View Options. There should be a checkbox for toggling the Library folder.
