The quick and easy answer to what files and/or other information do I need to keep copies of to sucessfully restore my system from the ground up:
All of them!
Actually, it depends on what you are going to do - and what type of disaster you are looking to recover from.
Scenario 1 - stupid user removes files he/she needed = Recover from backup tapes
Scenario 2 - stupid System Admin removes files the system needed = Recover from backup and/or rebuild server from scratch and add changed system files from backup, rebuild data from backups.
Scenario 3 - server dies - all disks lost = rebuild from scratch - reload system and data files from backup.
Scenario 4 - natural disaster - fire, tornado... = get new hardware, build from scratch, get backups from off-site, restore system and data files.
Realize that the system files you need to restore are the ones you change - stuff like adding new startup scripts that won't be there after you rebuild from scratch (rebuilding from Solaris cd). Changes to /etc/inittab, /etc/services, specialty files such as DiskSuite config files, Veritas vxprint output, Database configuration files, output from df -k command (showing how things were set up as far as mount)... these type things you may not need if all your servers are built the same with NO deviations. Example - all servers built with same OS - patch level the same - no changes to default system - no application DATA on system drives.
The most important thing you should realize - you need to backup the system and data files so you have something if you do have a disaster to rebuild from.
This also goes for upgrades, adding new software - they don't have to complete sucessfully - the only thing that has to work is how you recover from it. That will save your job more than anything.
