I use the functions.php code as is from the wp-includes directory, with my own smilies -- relevant portion below.
/**
* Convert smiley code to the icon graphic file equivalent.
*
* You can turn off smilies, by going to the write setting screen and unchecking
* the box, or by setting 'use_smilies' option to false or removing the option.
*
* Plugins may override the default smiley list by setting the $wpsmiliestrans
* to an array, with the key the code the blogger types in and the value the
* image file.
*
* The $wp_smiliessearch global is for the regular expression and is set each
* time the function is called.
*
* The full list of smilies can be found in the function and won't be listed in
* the description. Probably should create a Codex page for it, so that it is
* available.

* @global array $wpsmiliestrans
* @global array $wp_smiliessearch
