Introduction to Linux - A Hands on Guide
This guide was created as an overview of the Linux Operating System, geared toward new users as an exploration tour and getting started guide, with exercises at the end of each chapter.
For more advanced trainees it can be a desktop reference, and a collection of the base knowledge needed to proceed with system and network administration. This book contains many real life examples derived from the author's experience as a Linux system and network administrator, trainer and consultant. They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own.

Yes, the x86_64 is the 64bit version. I am running Slackware 10.2(32 bit OS) on my AMD64 laptop. I have had no problems as long as I used the test26.s kernel when installing.
The rest are 32 bit processor types.
i386 --> means it's designed specifically for basic intel architecture based on the 80386 (or 386 computers)
i486 --> goes up to architecture for 80486 (486 and above computers). NB: 386s might have problems with some of this
i586 --> as above but designed for Pentiums and above. Pre-Pentiums may have problems.
i686 --> Pentium II and above.
The 386, 486, 586, and 686 are/were Intel x86 (32 bit) processors. The x86_64 is AMD's (and Intel's) 64 bit extension to the x86 line that is backwards compatible with previous x86 chips. All will run on an x86_64 processor like your Sempron, however the non x86_64 packages won't take advantage of the 64 bit features of the platform. Likewise, the i386 binaries won't have any 486 or later specific optimizations/improvements, and so on.
The x in x86 comes from the fact that x is generally used as a "variable" and consequently, x can be 3,4,5 or 6. Intel's processor have been named 386, 486, Pentium, Pentium II and so on.
The fact that they are all backward compatible implies you can install a 386 distro on a 686, but not the other way around.
Also regarding 64 bit processors intel came up with a 64 bit architecture but it is totally not compatible with 32 bit processors, which means you simply can not run any os designed for 32 bit machines on these machines. I think they are called IA-64 (I believe if you try to run a 32 bit instruction set on a 64 bit process, there is a severe performance penalty.
However, AMD came up with an architecture that was 64 bit, but was essentially an extension of 32 bit. This was called x86-64, which means it can run 32 bit instructions just fine. Therefore, if you have a 64 bit processor (AMD Sempron, Athlon, Turion etc) it can run a i386 OS as well. Intel called their technology EM64t (Extended Memory 64 Technology).
Actually if you think about it, x86 itself is more accurately x86-32, since it is an extension of the 16 bit processor era of 8086 !
