What can we expect as far as recovery for my Mom's spinal surgery?

I was wondering if anyone could help me on here. My mother is having a decompressive laminectomy on L3 through L5, and a fusion at L4 & 5 a week from Wednesday.

I don't feel like we know what to expect as far as her recovery and the surgeon's office said they would call to explain a week before surgery.
My sisters and I (I live 3 states away) are organizing a schedule to take care of her the first few weeks or however long she needs it. She is 78, a widow and lives alone.

Very important: Are there any supplies we need to order now to help with her recovery (such as a stepping stool to get in the car, special bed, bathroom necessities, etc).

What about riding in a car? The hospital is 2 1/2 hours away from her home. Also, after about a week and a half after surgery, I need to drive her two hours to my sisters home where she can stay until she is doing much better. We are also working with their work schedules (one is a teacher for example and time off is tough).

If you've had this done, what is recovery like? Thank you so much!
