Help with WP.

Hey guys,

I'v bought this WP theme called "TheStyle", installed it and tried to edit it here and there and make some changes, but there are some thing I simply cant figure out how to do, and I know a little bit of HTML.

If you visit www.shakelab.com - that is my site - you'll see that I have put some stuff onthere for testing.

What I want to do:

First off, the three topics that are there are ones I made through WP, but as you see there are no space between the topics as there is in the original theme which is here - http://www.elegantthemes.com/preview/TheStyle/ - I have looked through all the codes and can't figure out where to make that space.

Second, I would like to remove the search function on the left side.

Third, if you press one of the topics on my site, I would like the "posted by *** on ***......." to be removed as well.

Hope somebody can help me.

Regards, XelisM
