Yes! Prior to Joomla! 1.5, only the text values of an Article and only for ISO-8859-1 encoding was allowed in the PDF rendition. With the new PDF library in place, the complete Article including images is rendered and applied to the PDF. The PDF generator also handles the UTF-8 texts and can handle any character sets from any language. The appropriate fonts must be installed but this is done automatically during a language pack installation.

Most Articles will be assigned to a Section and Category. In many cases, you might not know where you want it to appear so put the Article in the Uncategorized Section/Category. The Articles marked as Uncategorized are handled as static content.

To completely remove an Article, select the Articles that you want to delete and move them to the Trash. Next, open the Article Trash in the Content Menu and select the Articles you want to delete. After deleting an Article, it is no longer available as it has been deleted from the database and it is not possible to undo this operation.

Mambots have been renamed as Plugins.

Mambots were introduced in Mambo and offered possibilities to add plug-in logic to your site mainly for the purpose of manipulating content. In Joomla! 1.5, Plugins will now have much broader capabilities than Mambots. Plugins are able to extend functionality at the framework layer as well.

Well you are reading it right now! This depends on what you want to achieve. If you are new to Joomla! and have no clue how it all fits together, just install the sample data. If you don't like the English sample data because you - for instance - speak Chinese, then leave it out.

When you Archive an Article, the content is put into a state which removes it from your site as published content. The Article is still available from within the Control Panel and can be retrieved for editing or republishing purposes. Trashed Articles are just one step from being permanently deleted but are still available until you Remove them from the Trash Manager. You should use Archive if you consider an Article important, but not current. Trash should be used when you want to delete the content entirely from your site and from future search results.

The collation option determines the way ordering in the database is done. In languages that use special characters, for instance the German umlaut, the database collation determines the sorting order. If you don't know which collation you need, select the "utf8_general_ci" as most languages use this. The other collations listed are exceptions in regards to the general collation. If your language is not listed in the list of collations it most likely means that "utf8_general_ci is suitable.
