Make sure there is no space at all between the command bar and the chevron. I had just a little space between them and I was off about a dot on the ILS. I ask the sim guy why and he said "you have to tuck the chevron up into the FD command bar. As far as power settings, just ask.

Upon entering a hold I had to do a teardrop. When it came time to turn inbound I knew I had to turn left but the command bars were telling me to turn right. I turned left anyway and realized I didn't change my course to the inbound course. I still had it on the reciprocal. I recognized my mistake and ask the sim guy to set my inbound course. He did (he seemed to give a sigh of relief) and everything went fine.
