I installed the trial of Trillian 5.0 Build 22 (I don't know if the version 4 Astra is any different).
I successfully added my Facebook account so I can see my facebook news on Trillian and works great.

The problem is that I don't want to use the Facebook-chat, and if I disconnect the Facebook-chat the rest of the facebook stuff (news, events, groups, request) also disappears.

I tried by setting the Facebook status to Away; and I'm not sure if someone can chat with me if I choose that; but anyway I still have the contacts list full of people I don't want.

EDIT: Maybe I wasn't clear enough about the Facebook part. And that might be why some people fell this is off-topic. But when I talk about Facebook in this question, I'm not referring to the Facebook site at any point. I'm mean the Facebook plugin of Trillian (and it's not an user plugin; it's a built-in plugin).
