Congratulations on the amazing weight you've lost so far! That's pretty impressive, and you should be pretty darned proud of yourself!
Take a look around the recipes in the Phase 1 recipes section. You'll find some really good recipes for breakfast, lunch, supper and snacks to help keep you feeling full and motivated. Just take it one day at a time, and before you know it, you'll be finished with Phase 1. Two weeks goes by really fast, you'll be amazed.
As for exercising, do whatever you feel you can do in Phase 1. You can start out slow and increase your exercise time gradually as you start feeling more energetic.
Good luck, and come here for lots of support and motivation.
