Yeah, I think they're awesome. It's easier than typing in complicated URLs, and so much faster. I think companies, websites, bands, et.c. should use them more.

All of your data is preserved, you may have a problem with the widgets. Some of the themes do not support widgets in the sidebar. There are tutorials out there to add widgets to a theme if you happen to find a theme that you like that does not suport widgets. Change out your themes, hack them a bit until you find something you absolutely love. That is one of the main benefits of using wordpress over a lot of the other CMS's out there.
