dwebb,
Your best avenue is a quick call to the community standards office. I have spoken with them before on a theoretical question and they were very helpful. Phone number is (751-6719).
Prior link should be
www.districtgov.org not .com
My guess would be you don't have to get permission to change light fixtures. There is a requirement that you have a working light pole.
Also, Gracie, covenants north of 466 are different than south of 466. They can have lawn ornaments in the front and 'for sale' signs out front; not sure about house colors.
