Problems with related lists

Hello,

I'm running into a problem with Accounts, Products and Sales Orders with related lists.  For example, when looking at an Account Record, at the bottom of the page I have "Accounts" 2 times as a related list.  However, when I click on "New" in the second Account list it opens the Add New PRODUCT window.  I do want Products to be able to be associated with accounts, but why does it have Accounts as the label?  Also, my Sales Order field has the same issue.  There is also a Sales Order related list inside of a Sales Order.  I have attached screenshots for you.  Here is an overview of what I'm trying to accomplish.

We do photography for sports leagues and Marine Corps Units where we photograph their Birthday Balls.  Recently, we started selling small mementos that the Marine Corps Units purchase for every guest at their Birthday Ball.    However, we can sell mementos to Units that we do not photograph because they are all over the world.  So, we are adding the Products in Zoho and we want to create Quotes and Sales Orders for them.  Its a little tricky because every single Unit will have a different product because each item is customized and priced different based upon the number of colors on the challenge coin, etc.  I have it setup where it is working for me as far as adding the products and creating sales orders.  However, we want the Accounts page to have Sales Orders and Products available as related lists.

So, how to we add a type of record to show as a related list for another type of record?  I can't seem to find it.  

Also, why is Accounts showing 2 times but one is really Products labeled incorrectly?  

Lastly, why would an Account record have "Accounts" showing as a related list?

Please see my attachments for more clarification.

Thanks!
