Some questions about PIC

Hey, I would like to ask some questions:1. Failures: you want to expect any failure during the flight or at least for a first tryal a single engine failure after take off with PIC. What settings do you need to configure?2. Using the panel on a 757: a) ZFW - what values do we need to use?:( Is there a file for loading passengers and cargo like some other planes of ZFW is the same all the time? What should we configure for a 757-200?3. I am quite confused by the manuals. Can somebody explain me a quick way to load the panel, from a situation where everything is OFF to for example the take-off position?For now it is all.
