Best way to layer Custom Posts regarding structure and data

Hello All,

I would like to know the best method for layering posts when you need to swap back and forth between structure and data. For example, custom post type 1 has 6 custom fields, each field contains a value for the tab shortcode; i.e. [tab:data] [tab:credits] [tab:where to buy] etc – this type is standard every time the page is called and always the same post; then it needs to switch to another custom post type and select the data post it’s going to use based on what tag page is being called. Then it needs to pump a custom field from data post into the same display space as the base structure post, and then hop back and forth between structure and data, and THEN run a loop. Thanks in advance.
