I think, unless someone else wants to correct me
(probably Aq ;), that basically, the difference
between the processor specific packages is that they
are optimised for different processors.
For x86 packages, those optimised for 386 (i386) will
run on any later processor family (486, 586, 686), but
will not take advantage of the more advanced features
of those processors and consequently you should always
choose the one compiled for your processor family, or
the one closest. I don't think i686 binaries will run
on older processor families (corrections if required
I don't think there is anything inherently bad about
running i386 binaries as they are a pretty common
baseline used for many packages such as core utils
that need to run on any supported architecture, but if
there is one for your processor, then it makes sense
to use it. They have just been compiled with different
processor optimisation options.
Obviously, i386 is for the 386 and higher, i486 is for
486s and higher, i586 is for earlier AMD processors
like the K6 and K7 (I think) or higher and i686 is for
your common or garden Pentiums and Celerons. I think
later AMDs are 686 too but I might be wrong.
Corrections again welcome.

I assume from above you are using KDE so, spread
you're icons around and then right-click your desktop
and follow the menu down to Icons and then take your
pick. Probably align to grid and line up vertically
will be of most help.
It's probably a good idea to wait for your distro to
release their own packages tailored for their system,
rather than the latest and greatest from the
developers themselves unless you have specific reason.
If you don't know what you're doing, you may run into
problems. Don't let me put you of though if you really
want to, it's just that your distro vendors may rub
some bumps and edges off for you to ensure
Hope that helps,
