Selling on ebay is really easy. Sign up. Go to seller central and follow the prompts. Have your starting bid no less than what you will accept for the item. Unless it's something you really won't use, then I sell it as cheap as I can see selling it for. A good guide is to look on ebay and see what others are selling it for.
Also - here's a tip. When titling your item, call it what it is. For example. Your z-coil shoes.
Have the title
Z-Coil Shoes, Nurses must have tennis shoes sneakers
Never start an ad with 'an awesome.....' because it goes on first words as a search. Must have important stuff in the title that you would be searching for.
I have been selling on ebay for 7 or 8 years now (pretty much since they started selling other things besides the pez dispensers.
If you have any questions feel free to let me know
Also - believe it or not, yes there is a market for nursing notes - I sell mine on ebay by download
