Salaries: between 60 and ~100k for 0-2 years out of college (those are my friend's age ranges).
Rent: Highly dependent on where you live. Assuming you want to live decently in Manhattan, expect to pay anywhere from $1k (in Washington Heights) to $2k/mo (in, e.g. UWS) to unlimited for other areas for a 1-bedroom apartment (or equivalent). Obviously, this can be cheaper or more expensive depending on if you want roommates, location, quality of building and quality of apartment.
Living expenses: Obviously depends on how you live. Take what you pay right now and add 30-40%.
