"Do i have a good case ??"
*** Can you prove that the complex was negligent in their maintenance of the stairs?? If not, then you may have no case at all.

"The insurance contacted me do i get a attorney??"
*** No, they will not provide an attorney for you; however, you are certainly free to go out and get your own attorney.

"If i settle with ins how much"
*** Depending on a full review of the facts, 'damages' and injuries..... somewhere between $1.76 and the moon.
Seriously, no one can answer your question as we don't know what your REAL damages are. For example, if you are forced to miss work, are you a minimum wage dishwasher, or a $10,000 per hour cardio-thoracic surgeon.

The landlord has a duty to keep the premises in a safe condition, and must routinely inspect the premises to ensure that the equipment and fixtures are in the proper condition.

Stairs don't just collapse. I have a feeling that there were signs beforehand that that stair was not in good condition.

One strong recommendation that I would make that will help you no matter what you do is to photograph the stair and stairway extensively RIGHT NOW, BEFORE THEY REPAIR IT to preserve the condition of the stairway in the before-repair condition; that's probably going to be the best evidence of their negligence.
