This one is from a SL6 install. SL and CentOS are both RHEL. I keep the system utilities stock (the same as TUV, RHEL in this case), except for the use of

I am switching to SL over CentOS because (1) we do not have funding luxury to license the binaries from RH and (2) CentOS 6 is not yet available despite RHEL
6.1 already having been released. Other than re-branding, SL and CentOS both claim to be RHEL clones -- I know that the RPMs that work on RHEL release X work
just as well on both CentOS and SL of the same release.
(Why not SL over CentOS? A matter of history, not a specific choice. With the upcoming demise of Fermilab as a direct experimental facility, hopefully the EU
will continue to fund CERN and not be shortsighted as USA neoliberal Republican Tea Partists force upon the USA, and thus maintain support for SL.)
I did not reformat / , /var, /usr . Must these be reformatted?
Yes, otherwise you will have a mixture of the old system (CentOS5?) and the new
SL6 system on /, /var, /usr. This will definitely not work.
If you want to keep old data you have to do an update instead of an install. But I don't know if CentOS5 can be update to SL60 with SL60 install DVD. My guess
is that this will not work.
To be save make a backup before you format the partitions.
Will X86-64 SL6 allow me to keep these as ext2 (no journal)?
I think if you choose custom partitioning you can format your partitions with ext2. Just
curious, what's the reason to use "old" ext2?
