@ajs: The plus signs next to specialists allow for specialists to be assigned. These generate GPP for great people and give certain bonuses, and are very powerful. Beware, a citizen that is a specialist can't work a tile. To increase happiness and health, connect health/happiness resources(i.e gold and gems for happiness, corn and wheat for health). That will increase these, and you can trade with other civs for these resources.
