The centering is due to the global “td” style set within your theme (https://cloudup.com/c0p94YYuZlS) you can remove the text-align: center there to get a better overall layout there.
For the form fields, the quickest adjustment would be to set a background for the whole form. If I add the background and some padding like you see in the top of this screenshot (https://cloudup.com/c_kA59bkJ4v) it’ll show like it does in that screenshot.
Thanks for the information – but, as you probably guessed, I am a novice. I tried to find that bit of code in the theme functions.php but couldn’t seem to locate it so that I could adjust/remove. Would it help if i gave you my login credentials?

However, the code can be added to your theme’s style.css file. You can follow the conventions that you see there when adding the additional styles that you want here.
