NAV ERROR CAUSES LOC OVERSHOOT; CONFLICT AND TCASII RA.

Narrative

AS A CHK AIRMAN; I WAS OCCUPYING THE R SEAT WITH A NEW CAPT ON HIS IOE. I WAS FLYING THIS LEG (SJC-LAX). I HAD NOT FLOWN INTO LAX IN 3-4 YRS. APCHING SMO FROM THE N; WE WERE CLRED THE STADIUM VISUAL APCH TO RWY 24R. WX WAS CLR; VISIBILITY 6 MI IN HAZE (SMOG). LOCATED APCH CHART AND COMMENCED APCH; TURNING BASE LEG OVER COLISEUM AS PUBLISHED. ACFT WAS ON AUTOPLT; RWY 24R LOC ARMED FOR CAPTURE; IAS APPROX 210 KIAS. WE DID NOT HAVE THE SMO 084 DEG RADIAL SET IN OTHER NAV RADIO TO IDENT THE POINT AT WHICH THE 45 DEG TURN TO FINAL WAS TO BE COMMENCED -- AN OVERSIGHT ON MY PART. AS A RESULT; WE GOT A LOC CAPTURE ON A 90 DEG INTERCEPT WHICH RESULTED; PREDICTABLY; IN AN OVERSHOOT OF THE RWY 24R LOC. ALMOST SIMULTANEOUSLY WE RECEIVED A TCASII RA TO CLB; DISENGAGED AUTOPLT AND CLBED APPROX 400 FT. WE HAD A CONFLICT WITH AN ACFT ON APCH TO RWY 25L. BY NOW I HAD BEEN DISTRACTED TO THE POINT THAT I DID NOT IMMEDIATELY COMMENCE A TURN BACK TO THE R TO REINTERCEPT RWY 24R LOC. LOOKED OUT AND JUST BARELY MADE OUT A PAIR OF PARALLEL RWYS AHEAD (VISIBILITY VERY MARGINAL WHEN DOWN IN THE SMOG). AFTER APPROX 10-15 SECONDS THE 'NEW' CAPT POINTED OUT THAT I WAS LINED UP ON RWY 25L. CORRECTED OVER TO THE R AND MADE UNEVENTFUL APCH AND LNDG ON RWY 24R. FACTORS: 1) UNFAMILIARITY WITH VISUAL APCHS INTO LAX. 2) LOW VISIBILITY IN SMOG. LOST SIGHT OF LAX ON BASE LEG AND DID NOT 'LEAD' TURN FOR THE RWY 24R LOC INTERCEPT. 3) FAILURE OF LAX APCH TO CAUTION THAT SIMULTANEOUS APCHS WERE IN PROGRESS (RWY 24R AND RWY 25L). 4) DISTR OF TCASII RA (ALTHOUGH IT MAY HAVE SAVED US FROM A MIDAIR!) AND FAILURE TO XCHK THE LOC INDICATIONS AGAINST THE RWY N WHICH I WAS LINED UP.
