Domestic tranquility is basically the people being happy with the country and not being in danger. They were concerned about it because without it, it could lead to revolts and revolutions.
The colonists of America had very few opportunities to influence the government of England as they did not have any representation in the British Parliament (which was one of the factors that motivated the Revolutionary War). Because of this, they usually influenced the government through economic measures (ex. by disturbing trade) or through illegal means (ex. rebellions).

For example, by writing letters to their representatives, voting in local and federal elections, running for office and lobbying for a cause.
