Mimi just said what I was going to say. If you start using your granny gear (easiest ring on the front/left), you will get up those hills. Practice in a parking lot or other small street and go through all of the gears. You will soon find out what all of the sweet spots are.
You can get the chain back on by quickly getting the front (left) gear into the big ring (hardest gear) and pedaling hard. I have done this a few times, without even unclipping and it works.
