yes
gzip only compresses while tar's main purpose is to put a lot of files /
directories into one single file (usually a .tar)
actually, you can also compress with tar (to obtain a .tar.gz or .tgz)
ex:
tar cvzf yourtarfile.tgz ./dir_to_tar (creates a tarball of your dir)
tar xvzf tarball.tgz (recreate the hierarchy in the localdir from
tarball)

Linux soft RAID setup is done quite differently than Solaris

you have to know which program this agent is supposed to work with
(ie MRTG / SNMP, Big Brother,...)

I think most of the people here have done it at least once in their life
basically,
- make your choice of what config you want to have (according to the
help in menuconfig/xconfig or Documentation/Configure.help and the type
of use)
- make dep;make clean; make bzlilo; make modules && make modules_install
if you don't have the technical knowledge to make such configuration /
installation, just keep the kernel shipped with your distro (RH, Debian)
on the other hand, this might be very usefull if you have special needs
or use of your server (SMP, firewall, router) until pre-configured
kernel are shipped along with the distrib
