Xiaobaitu please in !!My Case to NSC pending; LG case to TSC pen

I am the primary applicant;

Nov 2005 Finger Print
April 2006 I-140 Approved
Oct 2006 my I-485 transfered to NSC for interview
June 2007 Infopass NC cleared
18 May and 4 June 2007 Address change requested by calling and Letter
12 June 2007: online case status update to Case pending at NSC after 8 month transfer;

March 2007 LG I-485 transferred to TSC
May 2007 LG Got 2rd finger print;

Two questions:

1. Anybody has this kind of situation: spouse's case transfer to different service center?
2. I still didn't get the 2rd finger print notice, how can I ask them to issue fingerprint notice?

Thanks.
