For comments, I'd suggest lj2blogger (or Blog2Blog). It's an app done by a guy called Paul Cooley and he's over on blogger and you c an ask questions and he'll answer, helping you make it work. His app grabs everything and then you can mirror it on WordPress to see the comments. Last time I checked, which a few months ago, WordPress was the only place that allowed you to import entries and comments.

LJArchive is good for backup and having a copy you can browse through of your journal on a local hard drive.
