I would suggest two things that have helped me a lot in my experience with CB:
1. Always list your platform and versions - (Joomla 1.5, 1.6, or 1.7, CB 1.4, CB 1.7 or whatever you are using) Each platform and version have slightly different setups, and you may not get an accurate answer without that info.
2. Use Firefox and Firebug to help you find the exact code that affects the area you are looking to change. Firebug highlights each section as you drop down through the code, and it will usually help you find the exact file and line you need to change in your code, to help you modify anything from template layouts to titles, etc.
