I'm no expert, but a mother of five. So this is not really an answer but a few suggestions you might want to consider.
She may be gulping down too much air. New nipple will hopefully help.
If you are giving breastmilk, it doesn't sound like she is nursing / feeding frequently enough. Go for frequent feeds, every two hours, with no restrictions. Let Baby nurse until she is content and finished with one breast before switching.
If you are giving formula, consider that Baby may be allergic to the formula and unable to properly digest it. This might cause vomiting, funny stools, and gas.
If you are not giving breastmilk, but would like to try, you still can!! Contact La Leche League for more information. You may find that Baby is happier on breastmilk.
If she is eating breastmilk the poop should be seedy. I hope the nipple change helps with the feedings and gas. Each lab has different "normals" and they vary by age & gender. Contact the lab for these ranges. If they have already told you if some of the #s are low/high it would be helpful to share.
No expert, but I do have 3 kids. Every bit of that sounds normal to me. Except the type of poop. Yellow is normal, but being little balls means she is a little constipated. May have to buy her a baby laxative. Newborns make tons of funny noises and for some reason always sneeze! Don't worry she will be fine.
