Welcome to the Forum!
You are learning well. Stress will drive your blood sugar numbers up, so will sickness. Exercise is one of the best ways to lower your Type 2 blood sugar numbers. Read the first three threads in the Type 2 Section, when you get a chance. These threads will validate most of what you already know.
Hopefully, the Android App will be rewritten to sync in the near future. You may wish to read the "Report Generator" thread. Twisty2 is trying to set that up for the Android App as well, but we have had trouble finding a Droid CSV file to compare it with, since none of us use the Droid. Maybe you can help him out.
