Regarding high availability features on EX, we currently have support for capabilities such as GRES today, as well as the usual network protocol level HA functions. Starting with our next software release (10.4), we will enable NSR for OSPF as well as a non-stop software upgrade function on EX8200 that will allow the chassis software to be upgraded without a system-wide reboot (each line card will restart individually, allowing network connectivity to be maintained during the software upgrade process). We do have a complete high-availability rollout planned for both the EX8200 and our Virtual Chassis products in 2011 which will leverage all the JUNOS HA capabilities. Details are available under NDA.

What option is needed in 10.0 to enable booting to the USB. Is there some pre-config that needed to make a out-of-the-box switch boot off they USB?

1) you can copy an Junos package onto a USB and use that to boot the switch.
2) If you want both config and image to be loaded onto a new switch, you can create a snapshot from an existing switch and use it to boot any number of switches (and tweak any box-specific configuration later):
user@switch> request system reboot media external
Hope this helps
