Narrative:

On approach into las; runway 26L visual. ATC turned us close behind preceding traffic. As we approached the FAF; our separation decreased to a point where ATC directed an s-turn on final for spacing. As we got really busy monitoring the turn altitude and airspeed in the s-turn; the 1000 foot and 500 foot call was late. As pilot monitoring; I inadvertently set vref speed instead of approach. Pilot flying caught and maintained extra speed. Airport conditions included gusty winds and wake turbulence on final.
