Good ideas!!! When you get the surgeries, you are going to be tired most likely, IBD people are more tired naturally and living without a colon can be tolling since a colon: absorbs water, electrolytes, vitamins/minerals. When your colon is gone its important to think positive and surround yourself with positivity. When I am down and depressed, I say out loud the things I am grateful for or I write them down, giving thanks and rejoicing are things that keep one's mental state healthy.
When working out: take it easy! Literally! A lot of people on this website have told me of their stories about exercising intensely and a lot of them have suffered consequences as a result of that, a lot of people will call their stories, "anecdotes" but I tend to believe people's stories on here, so I would just say take it easy and keep your weightlifting at no more than 25pounds. Exercise sessions, somewhere between 30minutes-1hr, remember: take it easy!!!
Staying hydrated and listening to your body is number 1 
Eating/drinking: Greek Yogurt and oatmeal are excellent foods for us, those are probiotics and prebiotics. Orange Juice, gatorade, lemonade, and cranberry juice are excellent hydration techniques. And Pedialyte
Make a list of things you need to get done for the day, that is how I stay organized.
