Help needed

Help! I need help for my blog new template!

You see, I wanted to change my blog layout to having two sidebar (I think the current one is wasting much needed space) but the problem is, my main post are overlapping with my right sidebar!

Frustrated ah! For those who are familiar with modifying template, could you kindly lend a helping hand?
