Newsgroup settings

I can't find the answer(I swear I use search) on the two question:

1.How to set up TBP to show full name of subscrbied groups
2.How to set up to show subscribed groups on opening(without clik + )

Many thanks in advance

P.S.
Assume this in local TB

// Don't abbreviate newsgroup names:
user_pref("mail.server.default.abbreviate", true);

// Remember news server states in folder pane:
user_pref("news.persist_server_open_state_in_folderpane", true);

But where to put in TBP?
