Make iMac boot disk on USB flash drive
Two things:

Can I simply do an OS install to a USB flash drive from disks that came with my new iMac and thereby create an emergency boot source?

How big a flash drive do I need to get to also load Disk Warrior or TechTools as well as the OS onto the flash drive?

Actually, a third thing:

Where could I find out this information for myself, i.e., does "it" say somewhere OS takes X amt of space, Disk Warrier, X amt of space, etc.?

Thank you all for reading and your gentle, considerate responses.

Welcome to mac-Forums

You can do but I would read up about it first. You will be looking at around 8-12gb usb thumb drive stick for the job.
Here is a link for a nice little tutorial about it:
Install & Boot OS X Leopard from a USB Flash Drive | Maciverse

Hope this helps

Personally, I would recommend an external drive instead. Then use either SuperDuper! (cheap) or CarbonCopyCloner (free) to create a bootable backup.

Three problems solved in one:
a backup
a bootable backup to continue working when the internal drive dies until you have the time to get it replaced
a bootable backup with all your tools to troubleshoot and/or restore the internal drive in case of a faulty update, app install, etc.

16 GB flash drive: $20-$40
500 GB external drive: $60-$70
1 TB external: <$100

Definitely go with the external drive like bobtomay noted.
I use CarbonCopyCloner on a 64GB thumb drive as a backup and you can boot from it. Trouble is, the thumb drive freezes up at times when using some apps.

If you do go with an external, FW connectivity can be worth the additional money if you are moving large amounts of data. For use only as a backup/troubleshooting device, USB will be fine.
