Customize wordpress template

I already have a blog installed. I'd like to make some modifications to it. Here's the list of things that needs to be done. 1. Limau Orange template fixed. (Right now it's shows an error -- **Fatal error**: Call to undefined function the_search_query() in **/home/alkalin1/public_html/blog/wp-content/themes/limau-orange-01/[login to view URL]** on line **2)** 2. Remove blog title from the post title. 3. Install the subscription form on the sidebar so that readers can signup to receive my free special report (I'll provide the raw HTML code and the image of the report) 4. Allow images in the post. 3. Install the following plugins: - AdSense - Amazon - Google Sitemap - Share This - Sphinn Button See my friend's blog for example at [login to view URL] I'd like to change color orange for green. I'm currently creating a logo that I'd like to insert in the top left hand corner instead of the orange square and the text.
