Translation of OTRS manual to pt_BR

Hello.

I started a translation task of OTRS manual. I followed the instructions from here
http://doc.otrs.org/developer/3.0/en/html/translating-docs.html and downloaded this file:

Revision 1.34 - (view) (download) (as text) - [select for diffs] 
Wed Feb 6 14:43:56 2013 UTC (7 weeks ago) by mg 
Branch: MAIN 
CVS Tags: HEAD 
Changes since 1.33: +457 -450 lines 
Diff to previous 1.33
Synchronized language version

I renamed the file to doc-admin.pt_BR.po and I'm working on it.
As I already have some work done I got some questions.
The first is, Am I with the correct file for translation or I picked the wrong one?
Looking deeper on the original file, it seams some lines aren't on the same order they are displayed on the web. This can be seen
for example on the line 1803 of the file, is that correct?
How can I send the translated job done? Do I have to send both .po and .mo files?
There will be a place where I can see how the work is going on?

Regards,
Carlos.
