Hi Melissa,

To remove date, author and categories from each post go to Appearance -> Theme Options -> Design Options Tab -> Custom CSS paste the following CSS code and Click on save all changes button:

.entry-meta .cat-links, 
.entry-meta .cat-links a,
.entry-meta .by-author, 
.entry-meta .date, 
.entry-meta .comments {
    display: none;
}

And to hide search form go to Dashboard -> Appearance -> Theme options -> Design options -> Custom header there you can find the option to hide the search form.

Thank you!
