I'm also new to Adium / Objective C.
I know this has already been mentioned but have you checked that your 
Header Search Paths
setting under Project ->Edit Active Target "Yourpluginname" is correctly 
set?
This was one of my main problems when starting out.

As a side note I am able to  have both
#import <Adium/AIPreferenceControllerProtocol.h>
#import "AIPreferenceController.h"

in the file GASendEmailSMSPlugin.m and I get no build errors (my Header 
search paths is ~/adium/Source)



Out of curiosity how are you planning to override the 
-userPreferredDownloadFolder method? Are you going to override it (by 
mangling) to
add an extra "sender" parameter?

 From your description you want the user's download folder to become 
sender-specific, have you considered looking into the
AIFileTransferControllerProtocol.h and the ESFileTransferController 
class to do the customization of the download folder when the file 
transfer happens?
It might be worth a try.
