"What are the following files for: boot.0302, config-ide-2.4.26, and map? Thanks, if it turns out that they are not needed, i'd like rm them to keep it clean."
config-ide-2.4.26 is the configuration file used for compiling your kernel. You need this only if you plan on compiling a kernel from source.
boot.0302 is a backup copy of the MBR before lilo was installed. You could conceivably use dd to copy boot.0302 to the MBR and restore the MBR to its pre-lilo condition.
System.map-2.4.26 is a map of the kernel that you can use to help you debug a kernel core file. If you are not planning on debugging the kernel you can live without this file.
