Hi, and welcome to the forums!
To answer your questions:
1) Go to Recent Foods and scroll down to the bottom of the list. Choose "More Foods". It will give you a day-by-day list of every food you've logged. Simply click in the box by each entry and click "Add" at the bottom. They will all be entered in today's log, afterwhich you may adjust the quantities if you wish.
2) To the best of my knowledge, you must monitor the nutritional info yourself--there is no "alarm" or warning. It's more like the speedometer on your car, rather than the fuel gauge--you've gotta watch it youself instead of an idiot light coming on.
