1) Ignore the log part, I forgot that that's optional. Basically when you install a ROM with aroma, at the end there is an option to save log so that we can see what had gone wrong if problems cropped up like yours.
2) No. What you do just ensured that your sd-ext and data partition is empty. As such you will not have any apps, but your ROM (or most of it) is still intact as the system partition is not wiped. However, Sense roms from 3.0 and above will store some files on the sd-ext partition as there isn't enough space, so when you wipe the sd-ext (factory reset), you are left with an incomplete ROM.
Edit: To write system partition go to Advanced> format system
