bigger inside than out
This trope of spaces with interiors larger than they appear from the outside is also present in Pynchon's 1997 novel Mason & Dixon:
- Our Coach is a late invention of the Jesuits [...] wherein the inside is quite notably larger than the outside, though the fact cannot be appreciated until one is inside. (p. 354)

the satanic Detective . . . everything in it that money could buy
This is a biblical allusion to Matthew, chapter 4, in which Jesus is led to the desert and tempted by the devil: "Again, the devil took him to a very high mountain and showed him all the kingdoms of the world and their splendor. 'All this I will give you,' he said, 'if you will bow down and worship me.'"
Also, similar to how Hector must have worked on Zoyd in Vineland: "Hector had been trying over and over for years to develop him as a resource, and so far technically Zoyd had hung on to his virginity... But... He kept coming back, each time with a new and more demented plan..." (p. 12 Vineland)

See page 154.

Ah, fuck no. Not this.
This shows how wrought up Doc is, since Shasta already told him she wasn't living there anymore (page four: "I moved out of the old place, staying where I can anymore, don't ask.").
"You're apologizing, Bigfoot?" "Ever known me to?"
Bigfoot, movie enthusiast and collector of Wild West paraphernalia, would almost certainly be familiar with She Wore a Yellow Ribbon (1949), where John Wayne's character says (repeatedly), "Never apologize, it's a sign of weakness."
Variant spelling of hijaz kar. Dick Dale's famous Misirlou is in fact a Greek tune based on the scale of Makam Hijaz Kar (E-F-G#-A-B-C-D#), and is playable on a single string of a guitar. Misirlou is one of the most famous of "Surf" tunes, thanks in large part to its presence on the Beach Boys album Surfin' USA and its inclusion in the soundtrack of the film Pulp Fiction. Wikipedia; Great 1963 clip of Dick Dale & the Deltones performing "Misirlou" from the 1963 movie A Swingin' Affair (Is that a young Al Franken on bass?)

Chantays, the Trashmen, the Halibuts
Three surf bands, two famous, one an anachronism time traveling backwards from the 80's. The Chantays famous for "Pipeline" is presented here on the Lawrence Welk show, May 18, 1963. The immortal Trashmen gave us "Surfin' Bird" and the Halibuts were a 1980s surf-revival group.
Coy and I should've met cute
A "meet cute"is a movie term that describes a contrived, humorous meeting between two possible romantic partners (e.g., a boy and girl bump into each other on the street then fall in love). In the 1934 film The Gay Divorce, with Fred Astaire and Ginger Rogers, in the song "Looking for a Needle in a Haystack", Astaire sings about finding the woman of his dreams whose name he never learned after they had had a "cute meet."
The Manson family murders play an important thematic role in this novel. Is it possible that Pynchon timed the release of this novel to coincide with the 40th anniversary of the tragedy (August 1969)?
Besides the associations mentioned here, Drano was rumored to be used to "step on" heroin (completely substitute for or augment the quantity of). Also, "Christmas tree meth" is slang for Green Methamphetamine produced using Drano crystals, although this might be anachronistic.

Amethyst is singing (albeit incorrectly) the theme song of the Mighty Mouse cartoon.
This passage is as significant for what is not on the television as it is for what is on. If Mighty Mouse is on, it's between 4:00 and 4:30 P.M., meaning that Dark Shadows, which shares the time slot on another channel, is not on. Which is not the case at a certain zombie-infested mansion.
Later in the afternoon
Afternoon, Thursday, March 26, 1970, the third day of the narrative.
Doc's cousin and lead guitar in the surf band the Corvairs, Oof also is a character in Pynchon's 1990 novel Vineland, playing essentially the same character:
- After a bit, Corvairs lead guitar and vocalist Scott Oof wandered in from the kitchen to join them, leaning on the doorjamb playing with his hair. (p.23)
Scott had been playing with a local group known as the Corvairs, till half of them had decided to join the northward migration of those years to Humboldt, Vineland, and Del Norte.
Pynchon migrated north along with many of the young people he knew from the South Bay to Humboldt county. /CW/ This passage reinforces the connection between Inherent Vice and Vineland. So Oof had remained in Southern California, while half the band migrated north to Vineland.
Oof's name also opens a rabbithole to the comic genius of P.G. Wodehouse. "Oofy" Prosser is a frequent co-conspirator in the Wooster-Jeeves comedies. "Oof" is also 20th C. British slang for moolah, pelf, wealth, geedis.
Note that many different surf music groups in many different times and places adopted "The Corvairs" as a nom-de-band.
The Big Valley
The Big Valley is an American television Western which ran on ABC from September 15, 1965 to May 19, 1969, starring Barbara Stanwyck, as a California widowed mother. Wikipedia As a major-league movie star during the golden age of Noir, Barbara Stanwyck co-starred with Fred MacMurray and Edward G. Robinson in Billy Wilder's classic Double Indemnity, scripted by Raymond Chandler.
This song from Scott Oof's band Beer points towards the San Joaquin Valley, which in 1970 was about the un-hippest place in the known universe.
