All you have provided is very useful, learning Linux from scratch is difficult...
I have a doubt about Kanotix. It seems to be a remasterized Knoppix for 64 bit.
As i am starting I prefer to start with knoppix, which is more developed, has more support, and in fact it´s a more "official and supported" version. As a prove you can find Knoppix in www.linuxiso.org among the mast famous linux distributions....thats why I was asking if it was possible to convert an standard Knoppix to 64 bit, to do it myself and learn. But this is far from now, I have tio install knoppix in my HD and start learning.
By the way, is it possible to say in the installation of Knoppix that you want Lilo in a floppy disk?

Thanks again.
