Thanks for volunteering to translate Joomla! to Uzbek language. In fact, all the people involved in creating the accredited language packs for Joomla! are all volunteers just like you and me.
The language code to use would be uz and the country code would be UZ. In essence, the full language reference would be uz-UZ, just like en-GB for English - Great Briton.
The translation could be done in the following order:
(b) Admin & Site as a package
(a) For the Installation, you could download the latest version of Joomla! 2.5 (which is 2.5.7) and use the files located in the directory \installation\language\en-GB as the reference.
In fact, you could copy the files en-GB.ini and en-GB.xml as uz-UZ.ini and uz-UZ.xml and start the translation.
You could release this first.
(b) Admin & Site Package
Right now there is not accredited Uzbek language pack (both Admin and Site) for Joomla! However, I noticed a language pack for Joomla! 1.5.20 at http://sourceforge.net/projects/joomla15uzbekla/files/uz-UZ_Joomla_lang_full_1.5.20.zip/download
Suggest translating Joomla! 2.5.x to start with. You could use the language pack 1.5.20 as a starting point.
Suggest reviewing the discussion http://forum.joomla.org/viewtopic.php?p=2614929#p2614929
that provides a tool to convert the 1.5 language packs to 1.7 language packs. This could translate around 60% of the strings. Hopefully this should help you out in your effort.
Another useful discussion would be http://forum.joomla.org/viewtopic.php?f=617&t=583461
Please use the text editor such as NotePad++ and use UTF-8 without BOM as the Encoding.
