Deprecated - Drupal core

i am using drupal 6.
i copied the default block.tpl.php and renamed to my block name with the right module and delta name, following this link; http://drupal.org/node/104319

now i can see these two lines

i have using drupal for more than 1 year, I am looking for a module could help to moderate my website.
the main thing i need it to help is to moderate comments and content type.
i have a lot of content type, and as you know every content type has its comments and moderator.
and also i have a forum.
which i really need is a module allow adminA to edit and delete comments in his field, and deny adminB to do this an adminA field, and visversa.

I want to add logout button at the top of page.How I can achive this.

i am new to drupal and have so many doubts. i couldn;t get the start yet and i am struggling. everywhere people are explaining high level things which puts me in more doubts. i was working in wordpress and which i learned in less than a week. this seems to be tougher. these are my doubts.

1. inside my theme folder there is page.tpl.php now how can i customize this page to arrange the contents according to my home page layout . the default code in that page has some regions and menus. which i was able to manipulate. i have created content types and uploaded content. this contents are appearing in the home page as a list with the title and a small part of the content with a readmore. how can i code in such a way that i can show the custom field values i gave while uploading the content. $node->$node->field_author[0]['value'] prints the value but how can i execute a query to get the results i want. i dont want all the content i upload to appear in home page. my home page has sections and each sections should show its on contents with the condition i give. is it possible? how? is there an option to execute database functions which we use in a normal phpscript like mysqli_query()? does that need to import any specific files?
