Just add this inside tooltips you will get it what to do.

tooltip: { style: { padding: 20, fontWeight: 'bold', fontSize: '30px', } },

Highcharts doesn't prevent from dataLabels overlapping. I have created simple module which prevent's from this, see simple demo: http://jsfiddle.net/menXU/1/

Use module by calling StaggerDataLabels(series);, where series is array of all series in chart object.

In the fact it's duplicate of this question, but I couldn't report this.
