To answer your questions:
1) The incidence and length of post-operative pain would vary depending on the patient. The average time to performing normal activities is 1-2 weeks.
2) 30% of people would require pain medications to control the post-op pain, in the rest of the cases, the pain most likely goes away on its own.
3) It is possible that back pain may be due to the surgery, however to be sure you should follow-up with your surgeon to ensure that a more serious complication (i.e. bile duct leak) isn't present.
4) If the pain doesn't go away, I would suggest follow-up with your surgeon. I repeat ultrasound should be considered to evaluate for this.
Followup with your personal physician is essential.

Yellow diarrhea is worrisome for C. difficile colitis. I would ask that stool studies be performed.
There are possible causes related and unrelated to the surgery: how far to go to investigate further depends on the severity, and the course it's following (getting worse, or better), and the presense of any other symptoms. Pancreatitis is a possibility, as is bile duct stone, or even a small leakage of bile. Also, even with the small incisions of laparoscopy, it can affect for awhile how one carries oneself, and any abnormal stooping, etc, can put a strain on the back. Back pain is common for a while after any kind of surgery on the abdomen. If I were her surgeon, I'd consider starting with a couple of blood tests if it weren't showing signs of improving soon.
