Hi flub,
I also find the Calibre software easier to use. You can also go in and change the metadata. I make sure the author is in both formats, so Jack London would also be London Jack.
Series and book number are easy to set. Finally if there is no picture I use something like:
http://www.fantasticfiction.co.uk
Which have pics for most books. Right click save to pc then select that when changing metadata. Easy peasey!
Oh and for us newbies this site looks great for free downloads:

You can select for Sony Reader. In fact I just downloaded The Call Of The Wild by Jack London. A book I read probably 40 years ago and fancy reading again.
Regards
Chris
