1. What do you mean by your icon refreshing? Are you talking about your account picture or your desktop and system icons? If you are talking about the system and desktop icons, sometimes you might lose a icon that is set when you switch icon packages and then restart your system. If this is the problem, you may need to rebuild your icon cache after switching packages. Or you may want to reset your icons to default before switching packages and then switch packages. You can find these options under tools in iconpackager. If you customize the packages and you keep losing the custom setting, you may need to resave the package as your modified version of the package. OR you can create a new package with a different name. But, if the custom icon is not present in the package folder, you may want to copy it there.
2. What do you mean by fix your name in the start bar? Are you unhappy with the choosen font because it is too pixelated, and you want a different font? If so, then you want to use Skin Studio to change it.
For user pictures, you can uncheck the box in the user override section for the start menu picture in the windowblinds advance configuration. WBAC is the button in the appearance tab of display properties.
I hope this answers your questions.
