Module development and code questions

I got drupal 4.7.x (by itself) and MyThreads (by itself) for my links solution.
"MyThreads" is a yahoo styled search engine. I want to synchronize the two! Yes. Yes I do.

I already started a reply/comment thread on accident so this is the TOPIC.
Kill me I can't delete the reply/comment!! Or I'd repost the whole thing.
(I am probably off topic even, but the IDEA hit me when I was reading the forum)

I have this in my menu hook:

  if (arg(0) == 'node' && is_numeric(arg(1))) {
    $items[] = array('path' => 'node/'. arg(1) .'/parts', 'title' => t($test),
      'callback' => 'parts_page', 'access' => user_access('access content'),
      'type' => MENU_LOCAL_TASK, 'weight' => 2);
  }

and then this function that it should be calling:

when i translate /en/node/12 into hungarian, it creats an en/node/13 article instead of making a /hu/node/12 as a pair...
the problem with this is that I can only change content according to the language preferences on the main page but not inside a node. so when I click on a blog entry in english at e.g. /en/node/12 and change the language, then it goes to hu/node/12 where the same english entry appears, only with hungarian menu items. a multilinguar site makes no sense like this... it should change the content with the language every time. The only way to switch is to put a link to translations on every page.
is it supposed to be like this??

another problem with this is that I cant use translated categories. when I translate taxonomy terms within one container (I cannot translate one term in container A to term in container B), then translated categories doesnt show up on the translation page at all. So I can only add different categories to a translated post if I made a separate container with a different language. So I cannot switch language through categories either. In fact this whole lang. switching thing ONLY works on the main page. :(((
translated categories have different node numbers too.

Multilingular taxonomy blocks dont work either, they dont appear on site and its also impossible to delete them.
I just reinstalled everything yesterday, I really dont want to do that again..

Hi!

I have 2 drupal sites. I need to retrive from 1st site node information and submit it on 2nd site (and from 2nd to 1st).

I'm newbie, so I looked for some examples and can't find it. I saw this post, but probably it is not a php-code.

Can anyone show me exapmles of code to retrive node information from 1st site to other site? I need to include this code in module file.

Should I enable drupal.module on this 2 sites if I want to use xmlrpc.php?

Is it possible to get a tagcloud that generates based on the results of one selected term? In other words once I chose Term A, can I see another cloud showing other terms available with pages with Term A on it?

I have a multilanguage site and translated categories using taxonomy and I cant use Movie Reviews module in multilanguage.
If I change from the default language when composing a review and push preview, it loses my language setting and doesn't come up with the language-specific categories as it supposed to. It says "If you change the Language, you must click on Preview to get the right Categories & Terms for that language" but it doesn't do that. So I can only write movie reviews in default language.
