It's weird that it took so long to index though - I also have around 650 ebooks and I moved them from Calibre to the PW in batches of 200 or thereabout, then just left the Kindle asleep and plugged into a wall charger while it was indexing. I did the last batch this morning and it took about 2 and a half hours to index 200.
I have also in the past transfered stuff to the K3 in fairly big batches and indexing was reasonably fast too (again Kindle asleep and plugged in)
