Wp Toolset View and Relationship adjustments

I need someone experienced with Toolset (Wordpress) and post relationships/ancestors to simply help render a view. It will probably take a person who is more experienced with Toolset than I am 15 min to sort it out. I have 4 content types. Regions. Suppliers. Products. Supplier reps. They are linked as followed: Regions > suppliers > products Regions > suppliers > supplier reps 1. On the product content template, I need to display a view of reps that belong to the same supplier as the product, as well as the same region of that supplier. 2. And vice versa... on rep page, display a list of products that the connected supplier is associated to. 3. The suppliers are using a unique code as their title, with a custom field for the supplier name. In my main filter I have a drop down for suppliers... I need that drop down to show their name, not their code (title). 4. When loading a supplier or supplier rep, if no region is selected, I need it to default to all regions.
