As far as goodies folder- I only saw the one bootanimation I choose when I selected it in rom manager for download. And in the goodies folder it was still zipped twice- had to extract the bootanimation.zip out of the cyborgboot.zip file (the cyborg boot is fairly cool- ) then copy and paste it to the data/local/ directory. If you can't paste it is probably because of read only being set on the folder, change folder to read write then paste.
From droid boots there are some cool ones like the droid shooting the apple! the longer the animation you select the longer your boot will take.
