By the 1958 ETT, the train is still listed in the ETT as the Oakland Lark, though it may have been listed in the public timetable as the Starlight if it had a name at all, since by that time the trains had been combined and the Oakland section no longer carried coaches. You are technically correct that the Oakland Lark never operated to 16th St. as the Pullman lines were discontinued May 1, 1957. I'm not sure of the last day of operation to the Pier, but it was during the summer of 1958.
Interesting is seeing 250/255 (correct numbers, my 249/250 were "spit wad" guesses) still there, most likely handling mail off of 90/91, the "Coast Mail". Within a couple of months 90/91 will be diverted to Oakland, with SF mail handled (probably a single car) by Commute trains 151/154 (Commutes got a separate ETT as part of the Coast Division). The third train listed on the Niles Sub, 335/336 is a scheduled freight train, still fairly common on the SP in 1960. The train numbers would have been carried in the indicator board of the lead locomotive.
The Oakland trains originated on the Martinez Sub at 16th St, operating "on signal indication" to West Oakland, under rule 82-A (pg 14 in the ETT). The time shown at West Oakland (not a station stop) is where the trains joined or left the Niles Sub. Trains 73/74 were discontinued May 1 1960.
