least enjoyable maybe the one between Hochdeutsch and Ashkenazi
Hochdeutsch generally means the standard German language (as opposed to regional dialects). Ashkenazi Jews historically spoke Yiddish. This may refer to the class differences between speakers of different Yiddish dialects, classier German Jews vs peasant-y Polish Jews.
The Galicia referred to here is the eastern European area that today forms most of western Ukraine and was part of the Austrian Empire from the late eighteenth to early twentieth century. During that time, the Jewish population of Galicia swelled significantly. After the Great War, Galicia passed to Poland. The Polish government prohibited both Galician Jews and Ukrainians from working in the state enterprises, institutions, railway, post, telegraph etc. These measures were applied in their strictest form. Galician Jews and Ukrainians experienced ethnic oppression by undergoing a forceful Polonization. In September 1939, most of Galicia passed to Soviet Ukraine. The majority of Galician Jews perished during the Holocaust. Most survivors immigrated to Israel, the United States, the United Kingdom or Australia. Wikipedia

echt Latina... boricua
Echt = German (and Yiddish?) for "genuine, real". Boricua = Puerto Rican.
Gracy Kelly...Rear Window...Thelma Ritter...Wendell Corey.
All references to Alfred Hitchcock's 1954 film "Rear Window." Oddly, the star of the film, James Stewart, doesn't get his name dropped. Thelma Ritter played Stewart's earthy, commonsensical nurse, a bit like the talkative Nurse from Romeo and Juliet. Wendell Corey played Stewart's skeptical policeman friend who helps save the day in the dramatic ending. You could say that Stewart, more than anyone else, is the one who 'saves' Grace Kelly from a murderer by calling the police at a crucial moment, and in general Kelly interacts more with Stewart than with Ritter or Corey, so I don't understand why Maxine is being identified more with them than with Stewart. Anyone have a better handle on this and can rewrite this entry?
Boris Kachka, writing for New York Magazine, writes that this building is "obviously the Apthorp". Although the Apthorp building does not have turrents and gargoyles from pictures available, its courtyard (photos here) closely matches Pynchon's description of the Deseret. Kachka writes that Pynchon himself lived in an apartment facing this building for years.
The etymology of the term "deseret" begins in the LDS scripture Book of Mormon, where the term is defined as honeybee, and used as an industrious symbol along with a beehive by Mormon leader Brigham Young.
carrying street Chanel bags
These could be Chanel bags designed for casual use. "Street" fashion is emerges not from studios, but from the grassroots, and is aimed at youth culture. OR Pynchon might be saying that those Chanel bags are knock-offs purchased on the street. It's ambiguous.
- It's the latter: a knockoff bag. Chanel bags start at a couple grand. From the context it's made clear that the characters can't afford them.
