HELP PLEASE: I need to slightly modify the JUST LUCID Theme

I would like to modify two things with the Just Lucid Theme http://demo.themelab.com/ and I’m hoping you can help me please…

1) I would like to eliminate the ‘V’ shaped logo at the top of the left sidebar.

2) Currently there is no space between paragraphs (even though I have one in the content of the posts and pages) and I would like to add a space between all the paragraphs.

Can someone please tell me where to go to make these changes?

Thanks very much.

Steve
