I haven't yet tested these but I am making a list of Scripts I think would be useful. They are all already in the database so just write them in the script field on the dialog editor.

k_con_dark -Checks to see if player is Dark Side
k_con_light - Checks to see if player is Light Side.
k_con_neutral- Checks to see if PC is Neutral
k_con_isfemale -Checks to see if player is Female
k_con_isjedi -Checks to see if pc is Jedi
k_con_ismale -Checks to see if PC is male
k_con_isscout -Checks to see if PC ias a scout.
k_con_issmug -Checks to see if PC is a smuggler
k_con_issoldier -Checks to see if PC is Soldier
k_con_npctalk- check if one of the NPC talk triggers has just fired.
k_con_pereasy -Perform and easy persuasion check
k_con_permed- Perform and Medium Persuasion check
k_con_talkedto - Returns true if PC has not talked to this NPC before
k_act_cmusic_off - Switches the music from the ambient background track to the combat music track
k_act_cmusic_on - The description for this is the same as the above but I assume it switches the music from combat to ambient. ;)
k_act_darksml small shift towards the dark side
k_act_darkmed medium shift towards the dark side
k_act_darkhigh high shift towards the dark side.

I'll add more as I find them.
