Found the solution pretty quickly after asking the question (and an hour after I started attempting to solve it):

Window > Preferences > General > Content Types > Text > JSP > Add (xhtml)

Makes the files be treated as jsp ones. Thus when they are opened with the JSP editor, the autocomplete of any tag library that has its definitions in .tld format ( and for example) works. Facelets, and facelets-only tags still don't work. Their .tld equivalents should be added somewhere in the projects. Facelet's tld can be found here.
