I just got a new C1000 as well ... and I chose to go with the beta 3 for now -- untill I learn the quirks of this distro.
beta 3 keeps the normal bootloader - so you don't need to overwrite it with U-boot. and most of it's bugs are documented and easy to fix.

initrd
tools
They are all tared together as one file when you download it - use winrar or utar to extract them and just copy to a SD card
