What I want to accomplish with Wiki

So I have been trying hard to learn how to use this wiki thing. Still have not gotten it all but Pegasus has been patient with me and has been trying to help/teach me as soon as possible. My initial goal is to write pages, categories and sub-categories within and make pages that will look something like this http://en.numista.com/catalogue/pieces12316.html
As you can see, there is the page with all the info and ebay items on the right panel.

My biggest question is: How can I show ebay listings on the right panel using a code? I can get the codes from ebay but don't know how to add them to the right side. And it would be a code for each page I make as the content will be different of course.

Lets see if anyone can come up with something and give me some idea, help out.
Thanks in advance yall.

To put things in the sidebar use:

Code:

---

[div] position="sidebar" | my sidebar content [/div]

---

If you don't want them in the sidebar, just to the right, use:

Code:

---

[div] style="float: right" | my column on the right [/div]
