Android Customization

I would like to have my android tablet customized for my specific needs. I have purchased an android tablet with version 2.2 that im told can be upgraded to version 3.0. I would like to have the android upgraded to version 3.0. But most importantly, when the device is opened, I want it to show my welcome screen with logo, music and some form of design. I would like to have some default android apps and phone settings to be uninstalled and have a few apps from the android market loaded, especially those that do not require to be connected to the internet to use the apps, this process, i can actually do this part by myself. I want to be able to install all my customized settings on other android devices so I would need an .apk file created.
