Ok well for the first one, go to the "safety" tab under the controls menu, and in there if you scroll down, there should be an "exclude home" option. Obviously you have to set a home location, but then it should work just fine.
For the second one, just go to your app if you have the latest version, and there should be the "schedule" option in the main menu. In there is the setting to precondition both the battery and A/C. You should be able to turn that off there.
Here is the manual, and you can go to "Using the touchscreen" and find both climate and Sentry settings there too:
