- automatic/manual install patches
- list patches installed and avaliable
- compare different configuration files on different servers
- clone existing servers, and do a "bare metal" install
- role back a failed update to original state
- change configuration files on several servers at the same time
- send commands to several systems at the same time
- send email regarding alarms
I have been checking out Redhat Network Satellite but i dont know it that supports all the things above. Anyone have any suggestions here it would be great, or is it a program like altirs i should use

To manage the patches, updates, rollbacks, etc, I think RH Satellite would be the best way to go.
For the other items, you may have to piece together something, but you've got all the tools you need to do it. For example:

is vague. Configuration files for WHAT? All going to use the same thing? If you're using vsftpd on some, and proftp on others, can't really compare the two. Best way would be to keep a 'gold' copy of ALL your config files, and write a simple script to diff the two on a regular basis, and push out a new one if needed. If you set up one user on all the boxes with passwordless SSH access, and SUDO rights, you're most of the way there.

Take a look at mondoarchive, mkcdrec, and systemimager. All are great bare-metal recovery/backup tools, and if you contact RedHat, they may have something specifically for their OS that you already have.

See previous comment about script to compare/change config files. Sending commands can be done using the fanout utility

Again, vague. Alarms on WHAT? And do you have an email system already set up? If so, simple scripts can be written and put in CRON to run at intervals, to check whatever you'd like, and send emails, restart services, etc. You can also check into setting up Nagios or Zenoss on that 'central' box, which can do all the monitoring from there, and alert.
