time machine bootable

No. The directory structure is not set up to be booted from. The files are all in the backups.backupdb folder instead of residing at the root of the drive where they should.

When you back up everything with Time Machine on an external GUID formatted drive, will you be able to boot from that drive?

No: but you can boot from the Install disk and then make use of Time Machine to restore. if you want a bootable drive as such (and it's worth having one) you will have to use something like SuperDuper.

You can, and it will boot, but remember that as Time Machine fills up the drive you will run out of space for virtual memory on that drive, so booting and running apps from it will become sluggish. This will happen when your free space on the drive drops to ~10GB or so.
