There is no desktop software like you are asking for. Desktop Manager (aka Desktop Sofware, as opposed to the Handheld, or Device Software) will sync the PIM data on the blackberry with several products, including a Yahoo account. If you want to manage the PIM data on a computer and sync with the device, Outlook really is probably the most seamless solution.
Find the options (or settings) icon on the applications screen, open it, look for screen and keyboard, and open that. Play around with the font to find what works best for you.
Also, open browser, open the menu, and select options. Browse around in the various options so that you know what's there. You will find a setting for the minimum font. Experiment with that until you find what works for you.
About volume, I'm not sure. Never dealt with that. I imagine you can lower the audio of the original files with software, then replace those files on the blackberry. But there's got to be an easier solution. Wish I could help.
