I downloaded the NENGEN Gallery plugin for wordpress for the pictures. For the library thing, there is a tab where you can create these sidebar items. Once you create it, you make a text widget and copy it in there. I have my blog hosted by David Lamb, not wordpress anymore. They may have you restricted.

Okay, not only does your Library Thing work (I can't get mine to) but now you have a cool photo feature. I am so jealous. How do you do it??
