SSDI benefits can be offset by public disability benefits or worker's compensation, but not by unemployment insurance benefits. So if it is truely unemployment and truely SSDI, there will be no subtraction or payback of unemployment.

If you also have an SSI claim, all income will be factored in to determining payment, including unemployment and any other money recevied.

Reasonable to expect 30-60 days for first check, 60-90 for retroactive benefits. SSDI claims are paid out of the payment center in Maryland. It is not a state issue. Local offices are run differently within a state, even within a city. SSDI is a federal program. There are state employees who make disability decisions, but once the decision is made, the difference in processing time becomes based on the backlog in your local office, the backlog in the payment center mod, and the individual claims reps and claims authorizers assigned to your case. Not a state issue.
