Help With Coding

[rickwphotography]

Hello, I am a complete dunce at computer stuff, so maybe somone can help me. What I want to do is eliminate the pbase bar at the top and also to move the titles on my AlexC pages from the right hand margin over to the center of the page. Is there some type of coding I have to use. And if so, where do I put it and how? I want to thank anyone for their assistance.
