It depends - whether you're a private seller or a business. Private sellers pay a 'flat fee' of 10% up to a maximum of £75.00 (UK currency - since I'm in UK). Business sellers pay between 5% and 12% - depending on the category. The exception is property - where the fee is zero.
There is a "seller's fee" charged on transactions. You as the seller get what is left after deducting this fee from the amount the buyer payed.

Depending on whether or not you have committed fraud (ie saying you didn't receive a large ticket item when you did) and the dollar amount they can file suit against you or try and have you charged with fraud by deception
One can sell a car on eBay by paying an insertion fee to list a vehicle on eBay Motors. If the item sells, the seller is also charged a final value fee. There is no additional fee charged after the listing has ended.
Not much: it is what we call an ion. As a charged item, it will be drawn to any item that is differently charged to itself - Lacking an electron, it is positively charged, so it will be drawn to an item that is negatively charged (a surplus of electrons), neutrally charged (the right number of electrons), or even less-positively charged. As soon as an ion comes in contact with such an item, it will grab an electron from that. Be that item a larger atom or molecule, a spec of dust, a wall, or you. It will then be an ordinary, uncharged oxygen atom. What it touched will then be charged slightly differently, and will be drawn to another charged item, until everything is charged the same. So for an atom, being short an electron is not a big deal.
the number of your item in the ebay history
No it won't affect your credit report unless you happened to charge the item to a credit card and not pay for the item once charged to the card.
Yes, you can be charged for something that you damaged even if it was used. The fact that it was used and not new only goes to the amount you will be charged, not whether you will be charged. If you did damage a used item, the charge should be for what the item was worth in the condition it was in before you damaged it. The landlord cannot charge you what it cost when it was new.
Technically, yes, you could be sued. If you send the item in the mail, or your customer sends the money in the mail, you could potentially even be charged with a federal crime (mail fraud).
A listing on eBay is a description of an item someone is selling on eBay. A listing includes the user name of the person who is selling the item, the price of the item, the shipping cost of the item, the location the item is shipping from, and a description of the item being sold. It will usually include pictures of the item, other items that person is selling, and how many people have looked at that item. Basically, a "listing" is the eBay term for what you might normally call an "ad", or an "auction".
eBay is an online market place and not a betting and gambling website. You do not "bet" on eBay, you "bid". This means that when you find an item that you like, you enter your bid amount (how much you are willing to pay) and then usually, someone else will place a higher bid against you, because they are willing to pay more. If you think that the item is still worth more money, you can place a higher bid, and so on. The person that has the highest bid amount showing when the auction ends wins the item and then has to pay the seller for it.
to buy an item if you don't have a credit card you can ask someone to get it for you and pay them the amount in cash, that is only if they accept
