Standard Forms: Which Ones?

I'm updating some procedures and policies in my very small firm, and am contemplating how many standard forms I should keep in my workflow. I have two main questions:

A) How many do you think is ideal? B) Could you get away with less than 10?

This is more or less the landscape I am contemplating implementing:

1. Project Initiation Checklist (includes intermediate and final check documentation)
2. Risk Assessment
3. Letters of Assurance
4. Request for Field Review / Instructions
5. Field Review Report
6. Supplemental Information
7. Independent Review Checklist

I'm open to all suggestions on how to think about this better!
