feeding questions, need experienced pro feeding moms opinion?

When I have my baby in May I want to feed. I want to do this for the Nutritional benefits as well as financial savings since I make too much to have WIC. Will I start bf when in the hospital? Do i tell the staff i want to bf and not to give formula to the baby? Also, I feel very strong about not BF after age one. How often does a newborn (like 1-8 weeks old) feed? I heard when you bf its every one and a half hours. That seems really demanding. Or is it 3 hours like formula fed babies? When I go back to work (3mo later) do i have to pump at work in order for my supply to not run out? I won't be able to do this. I can pump before work but thats it, do daycares like feeding pumped milk or will they throw a fit? Please give me any advice you can as well as some answers to my questions.
