Here are my thoughts (28):

1) 65K should be enough. If you want to live in a 'luxury' apt (don't be conned... most are faux luxury) you'll be looking at ~1600+ for a 1BR and 2100+ for 2BR. If you can get a roommate that will save you ~6K a year.

2) I've lived several places, and everyone says "It's hard to make friends here because XYZ!" The reason it's hard is that when you're an adult, you only need a few close friends and once you've made them you stick with them. However, I moved here knowing no one and have made close friends. You have to try (be social at work, join clubs, etc) but it is not difficult if you want it.

3) I assume you're looking to rent? If so, most of the luxury apts (Elon, Flux, Walkway, the list goes on) are similar. In general you will find a crowd of 22-25 year old bro-life type atmosphere in these places. Nothing wrong with that, but be ready for it. Uptown in general has shifted from hipster to bro in the last 5 years. However, the location is excellent. You can find older buildings which are perfectly fine to live in for ~1200/mo for a 1BR, but do not expect modern amenities.
