Dry ice
Does anything need to be placed under dry ice in a cooler to protect the cooler?

Putting regular ice with dry ice is unnecessary. The dry ice is colder than the regular ice. You're not helping any by adding it.
Dry ice "melts" by air flow. If you compartmentalize it to reduce air flow over it, it will last quite a long time
The water ice insulated the dry ice and kept it away from things it might damage. In addition, when the dry ice all sublimed the regular ice was still there and lasted for several days.
