B737-700 flight crew reported their aircraft overshot approach into a TA with parallel traffic. Also...

Narrative:

The captain briefed and we set up for the ILS prm (precision runway monitor) approach. We both selected the localizer in our active navigation radios. I don't know when he switched his frequency to the VOR after his brief. I verified I was 'tuned and identified.' approach gave us the final turn to intercept the localizer and cleared us for the ILS prm approach. After the clearance; I saw that his localizer frequency wasn't tuned correctly and I verbalized he needed to switch back to the localizer frequency. VOR/localizer was engaged prior to him switching to the localizer frequency. While he was selecting the localizer frequency; I was verifying it was tuned and I did not notice if he had re-engaged VOR/localizer. Approach switched us to tower. As I switched frequencies and selected the final monitor in VHF 2 we received a TA.I saw company turning onto their localizer for the left runway; then I saw we had blown through our course and verbalized he needed to correct back to the right. At the same time; final monitor asked if we were on frequency. I responded with an affirmative; and he cancelled our approach clearance and instructed us to descend to 3;000 feet and then said to report re-established on the localizer. The captain disengaged the autopilot; but was not descending. I verbalized 'descend now' and I engaged vertical speed at a 1;000 FPM descent to give him guidance. The final monitor asked; 'do you have the runway in sight?' we did. He cleared us for the approach; and I noticed the aircraft was turning left again. The captain didn't realize he had not re-engaged the autopilot. I told him 'you are still hand flying; turn right.' at that time; the final monitor queried us again. 'It looks like you are lined up for the wrong runway.' I confirmed we were correcting. He issued our landing clearance. After landing; we were cleared to taxi via the [taxiway] loop. Upon reaching taxiway and prior to my check-in with ground; we heard a stuck microphone on frequency. The captain continued to taxi while I attempted to contact ground. I contacted ramp to inform them of the stuck microphone on ground frequency. The ramp controller cleared us in and queried 'so you didn't contact ground?' I confirmed that we hadn't because of the stuck microphone. We taxied in and parked.

Approach gave us the final turn to intercept the localizer and cleared us for the ILS PRM Approach. After the clearance; I saw that his Localizer frequency wasn't tuned correctly and I verbalized he needed to switch back to the Localizer frequency. VOR/LOC was engaged prior to him switching to the localizer frequency. While he was selecting the localizer frequency; I was verifying it was tuned and I did not notice if he had re-engaged VOR/LOC.
