Hello,
There was alot of replies to your post, but I wanted to make sure you 
were clear.

If you do nothing, you will stay at SL 6.0 and get all the latest 
security errata for SL 6.0.  You will not get any bugfixes, only 
security updates.

If there is a package that you are worried about being upgraded, whether 
for security updates or not, you have two choices.
1 - Edit /etc/yum.conf and add an "exclude" line (man yum.conf) and it 
will never be updated
2 - Edit /etc/sysconfig/yum-autoupdate and add the package name to the 
EXCLUDE line.  Then the package will not be automatically updated, but 
you will be able to update it by hand via yum.

If you want to later update to 6.1, or 6.2, or the latest version, the 
webpage is now up that tells how to do that.
http://www.scientificlinux.org/documentation/howto/upgrade.6x
the short version is
   yum --releasever=6x update
