This site indicates there is likely no known version of Ubuntu that works on a MacBook Pro 1.1:

Albeit, that is not directly stated. I would be more accurate to say "there are no known Wiki's that tell you how to install a particular version of Ubuntu on a MacBook Pro 1.1"
I have a MacBook Pro 5.1 and I have had success installing Linux Mint 17 Xfce. The Xfce desktop works better for my mac than the other desktops.
I believe Linux Mint 13 is a fairly stable OS for older computers - you might want to try that one out.
I did not use rEFIt or rEFInd.
When you boot from the DVD, there is a "Window" option and an "EFI" option. If you have an EFI based system (and not a BIOS based system), use the EFI boot. My mac required the EFI boot.
Another error I experienced when booting required me to add "nomodeset" to the grub boot command. (I suspect this is the point where you "choose Ubuntu and begin start up I have a choose cd-rom screen, and my keyboard is locked.") To add nomodeset, press the "e" key when you see the grub screen & your desired boot option is highlighted - this will take you to a screen with the boot commands behind that option. Find the line (probably second from the last line) that contains "quite splash --" and modify it to read "quiet splash nomodeset --". You can tinker with deleting the word quiet and/or splash, but leaving them in generally works best for me.
I actually saved all of my steps for installing Linux Mint 17 Xfce on my MacBook Pro 5.1 in an Excel sheet. If what I gave you is fruitful, I can post everything else I did. It might take a few days for me to do that though.
