Heres my take on your questions....I am sure someone with more technical knowledge will chime in as well. The AP is not a boost controller that you can just set. It does allow you to monitor boost pressure on the AP. The AP allows you to download pre-programmed (parameters are locked as part of the map) maps to your existing ECU. The map modifies sections of the ECU's programming to give you more power (timing, boost, AFR..etc.). Because you are using the stock ECU it will throw CEL's if you go above safe parameters set by Subaru (ie EGT). The maps shut these CEL's off so that your ECU does not throw a CEL and go into a safe mode which will take your power gains away. The maps are on the conservative side, so chances are you will not find dangerous EGT's, they will be higher than stock but not off the charts dangerous. Iif you add mods outside of Cobbs recommendations you could have issues, or if your car is not maintained well you could see issues. Gauges will allow you to monitor important engine parameters and make sure all is well. A boost gauge and EGT are definitely the ones to start with. It's the old ounce of prevention.....

Good Luck
