Congrats on your new bunner, and welcome to PT! 
1. The first week or so she may want to be left alone, but after that bunnies need a minimum of 4 hours of exercise per day, so keep her out as long as you can. When she is fixed and a little older, you can even give her free range of a bunny-proofed room. That is what I do for my bun. He runs around during the day, and I have a big enclosure for him at night.
2. How old is she? Veggies shouldn't be introduced until they are 12 weeks old. If she is over 12 weeks, then that sounds fine. I wouldn't give spinach every day though, because it is high in calcium. Try parsley instead. Until she is 6 months old, she can have unlimited alfalfa hay and alfalfa pellets. Her diet should be about 70% hay, so she should start eating more of it soon.
3. Baby bunnies don't litter train very well at first, just like any other baby animal. Once she is 6 months old, get her spayed and it will help a LOT with litter training. The best way to do it is to get a large litter box, fill it with compressed wood pellets or a different paper or aspen based litter, put hay in the litter box for her to munch on, and take out all other litter from the cage. Its important that the only litter in the cage is in the litter box, because otherwise it will confuse her. You can put towels, blankies, newspaper, ect in the rest of the cage.
