job - How to balance previous works and current idea in a research plan?

I am writing a research plan for a tenure-track position. I wrote a 5 pages of three sub-plans based on my previous successful works.

1. 
   

   50% of each sub-plan is about my previous works, and 50% is about how I want to continue them. Is it the correct balance?

   
   


2. 
   
   

   Is it required to cite my previous references in the research plan or the search committee see them in my CV?
