Hi davey486, welcome.
I'll try to help with the Docky problem:
1-Right-Click the Docky Button. Choose Preferences.
2-After the settings window is up, click on an empty area of the dock you want to setup, the bottom or the one on the side.
3-The settings window will then allow you to change the settings for that specific dock.
4-Close the settings window, and then repeat the process for the other dock.
About your installation, have you downloaded the 32 bit version? On a 64 bit machine, you can install any of them, but on a 32 bit machine, you can only install the 32 bit version. Also, why type at "boot:"? Doesn't the menu from the live cd show up? It should appear a menu, allowing you to choose what to do, go into a live session, install and several other options.
Please report back, or if you need more help...
