As a day care provider, I have no idea what nanny rates would be especially as they vary by area. But I do have some thoughts about the situation.

1. Because you are on call, effectively you are working exclusively for this family. Without a schedule giving you advance notice of when they need you and when they don't, you are unable to have a second part-time job because there's no way you could predict when you would be available to work it. These parents need to understand that you are solely dependent on this role for them for your whole income. If they don't want to pay for your availability for short notice work, then they need to give you a schedule at least a week in advance. How the hell do you even plan any down time? Or social events? If they want exclusive rights to your time and for their requirements to be priority, then there's a cost for that.

2. The should be paying for your bus pass because they expect you to take her to school on public transport and also sports activities. If you had your car, they would be paying for your gas expenses. While I can see it being your responsibility getting to and from your location of work, the in between trips are due to their needs.

3. Overnight care should be an extra fee. You are giving up your evening and your night and your time has a value. For reference, if a day care child were to be here overnight - it would only be agreed to based on my availability and there would be an additional fee of at least $100 for an overnight.

4. If you are sick, you are sick. Period. If your "friend" doesn't understand that you don't want to be looking after her child when you are vomiting or have an upset belly, then you need new friends.
