Here's some more scans of the Wii golf game which reveals more costumes that you can make your characters wear. Those playing the PC version already can enter passwords to unlock even more costumes. Dead or Alive fans should recognise the Katsumi costume and there's also Hyabusa Ryuu from Ninja Gaiden.
Also there's 3 modes you can play - Story Mode, Stroke Play and Match Play. Stroke Play has you competing on 18 hole courses against rivals to reach the higher ranks and Match Play has you playing individual rivals to unlock new ones.
