Customizing Toolbox

I need to do three things to the Toolbox Theme. a)Move the post-date to right below the post-title. Right now it is below the post. Which PHP file is it in. b)Show only a Summary of Post. I need to have the viewer click on a text link, “Read More” to view the rest. c)Lastly, I would like to Hide the Comments. Viewable when the user clicks on a text link.
