I don't know that you have any actual content. At least not if you are trying to create a foundation for an individual moral and ethical system. I don't accept the idea that you can reduce motivation to the preference of comfort over pain. Some quick reasons:

A) A lot of moral choices don't break down to a pain/comfort dichotomy
B) The pain or comfort that people experience often results from things beyond their control.
C) Pain and comfort can be managed without making external choices, and without making moral choices.
D)People frequently make choices that they know will cause them pain, and forgo options that are comfortable.

And that's without getting into anything related to the concept of "lying" or the validity of basing choices on our interpretation of the motives of animals.
