You're doing a fair amount of work and with your stats, 1900/day should be fine. Your BMR is going to be around 1600 and with your current activity level, your upper range will be around 2500. All of this combined should be a great starting point for you to start seeing the results you're after. Your level of conditioning prior to starting this lifestyle change will determine how much muscle increase you're going to see early on. I wouldn't be at all surprised if the scale doesn't, at first, reflect the amount of effort and time you're putting in. For this reason, I think it's best to use the mirror, clothes and friends to judge your progress.
