You ask for information with commentary. This means that online joseki trees without commentary or pure game collections drop out. Famous? It depends on what you mean. You mention two particularly difficult joseki branches but maybe you also mean 'frequent' / 'popular'. For specific difficult josekis, surely there are specialised joseki dictionaries in Asian languages only showing many tactical variations. If you want such for all "old" josekis, read the Nihon Kiin Joseki Dictionary (expensive). For still quite a few josekis and mostly tactical variations as commentary, read the Ishida or (fewer variations but slightly revised) the Takao. If you have too much time for searching literature and money, you might buy many game commentaries in books and journals and build up your own collection. If you want commentaries on strategic decisions, purposes of moves, evaluation and every relevant strategic aspect, read my Joseki series. Nevertheless, it cannot hurt to also study commentary-free sources: the GoGoD games collection accessed by the shape database tool Kombilo.
