Is donating booklets of "A Thousand Years and a Year" considered a propagation on behalf of the Prophet, peace and blessings be upon him, in compliance with his saying, "Convey from me even a single verse"?

The methods of conveying the message are not limited. Spreading books of knowledge and admonition that conform to the Sunnah (definition) is one of these methods and is considered an ongoing charity (Sadaqah (definition) Jariyah). The Prophet, peace and blessings be upon him, encouraged conveying the message, "even if it is a single verse." So, if a book contains a thousand established Sunnahs and the enquirer gives it to someone who reads it, then he would have conveyed a thousand messages from the Prophet, peace and blessings be upon him.
