Installing Drupal

not really an installation problem but i wasn't sure where else to put this. i've got drupal up & running pretty well, but for some reason whenever i search for something i only get 1 result returned. (it seems to be the the node with the lowest ID number also)

for example, i've got hundreds of comic reviews here:
http://www.buzzscope.com/pcs/taxonomy/term/1

Installed drupal 4.6.3 the input formats do not show up on the page: administer->input formats.

I think there are 3 input formats by default: 'Filtered HTML', 'PHP code' and 'Full HTML'. But They are missed. Also they do not show up on the page of 'create content'.

Anything wrong or some module missed?

i have installed webform according to the INSTALL.txt
i can create a form, and when it is submitted the contents are sent by email correctly.

however, i also get the following errors instead of a confirmation message:
warning: _webform_process_submit(webform.inc): failed to open stream: No such file or directory in /www/drupal-4.6.3/modules/webform.module on line 748.

warning: _webform_process_submit(): Failed opening 'webform.inc' for inclusion (include_path='') in /www/drupal-4.6.3/modules/webform.module on line 748.

I installed Theme_editor module and Image module. Both modules seem to use the File system path, which I set to a directory which is not accessible over the web, because I use Private download method.

Theme_editor copies the selected theme to a subdirectory of this file system path, instead of to the themes directory, so the theme is not accessible.

Undeffined _form_get_error in legacy.php
Has replaced the given function on form_get_errors like has ceased to swear. Has added Conent type. I press Create Content-> Form there are mistakes:
warning: array_key_exists() [function.array-key-exists]: The second argument should be either an array or an object in z:\home\deprofy.lan\www\modules\taxonomy.module on line 501.

Here is the error i got when I tried to log in the first time, after registering:
