Theme development

I have two Field related questions that have to do with two different situations.

Situation 1:

Within my main content area I want to display two fields within one div. I created a custom field (simply a text field) for my content type that allows me to manually enter the name of the person that should receive credit for the page's content. This is called the "created by" field.

Here is the code that I used in my field--field_created_by.tpl.php file that allows me to add css around the field:

I would like to align exposed filters vertically on the side bar.

Furthermore I would like to style each dropdown in a way I can have a link under the dropdown which pulls a pop up to offer more explanation about what is being filtered.

I am unsure on which .tpl file to use or where to even find this file

Hi all,
I have a problem with files uploaded in theme appearance settings.
Drupal sometimes deletes my uploaded files but I didn't find exactly in which circumstances.

Here is my code for the upload field theme settings:

I'm using Drupal 6.

My site does not index. In "/admin/settings/search", appears a message saying that 0% of my site is indexed. Because of that, my search does not work well.

Furthermore, I have tried a lot of times run cron manually, but did not work too. What do I do?

There is a gallery formatter in my website. images that are included in this gallery are from album content type. I'm trying to theme the page that must display this gallery. to do so I added this code in template.php

I am integrating color module with my theme. After much work, I am successfully generating a new stylesheet by modifying the colors on the theme setting's page, as you would expect. However, because the generated stylesheet (named something like files/color/my_theme-a87738dd/colors.css) loads somewhere in the middle of the long list of stylesheets, many of the colors are overridden by the stylesheets that come after it. Because of this my custom colors don't appear to take affect (even though they are there).
