No, bluetooth has nothing to do with the mobile network. You can see this if your phone will let you use it without a SIM card (some phones don't though)... bluetooth will still work just fine. Your network provider has no way of knowing what you're doing with bluetooth. The only people who can possibly know are people within bluetooth range (around 20 metres, depending on the phone and environmental factors).
It has to be a Bluetooth phone and you have to have the Bluetooth turned on. You then have to pair it with your iMac.
Skype chatting like video does not show up on the normal phone bill. If you call a contacts cell phone from your account on skype and you do not have credit it will not go through. If you have credit, it will show up on your phone bill. But regular videos chats do not show up on your phone bill.

Not normally. The airtime of your call is billed by your cell service provider, not the person to whom you are calling. What will show up on "their" phone will is the airtime "they" used on "their" plan to talk to you. "They" would have no way of knowing what the charges were for "your" call to "them."
