Congratulations, and hang in there. Our twins were born last year at 26 weeks, both right around 2 lbs.. we were there for 100 days. Kids came home with no machines or funny business though; we were richly blessed.
I will say this: once they come home, every single chance you have to spend money to make something easier or more convenient, DO IT. Get lots of extras of stuff so you don't have to clean things as often. Our kids needed formula added to their milk to boost the calories.. so we were constantly mixing up milk and measuring stuff out, etc. Now we have so many of everything we wash/prep/refill bottles once per day and that lasts us all day. Never be in the situation that there is a chore between you and giving a baby what it needs RIGHT NOW.
Good luck!
