EBay is a venue. It no more 'takes over' your copyright than a B&M bookstore would if it were selling your books.
However, digital items can only be sold on eBaydotCOM under the Classified category. There is very little Seller Protection there. Read carefully the selling agreement.
No you have to have a credit card and it cannot be a prepaid card. The reason is that eBay will charge your selling fees against the card as well as use it as a rough and ready confirmation of identity.
Since you already have Paypal that is all you need. At some point you will be asked to add a bank account. This means you have been very successful and have higher sales than eBay originally expected.
This is a member to member board. EBay employees only occasionally drop in.
If you want a specific question answered by a sensible employee, check out the Weekly Chat . Sellers and buyers ask specific quetions of employees at one pm EST on Wedensdays.
