Olendirk,
Follow the normal Go-around procedures and callouts. KISS (keep it simple stupid). This will avoid confusion.
One thing though, but a very important one...
As "Shiny side down" said, don't wait to set missed app. alt. in the window after glideslope capture, but be always aware that if you are light and the level-off alt. is close to your present altitude (in your situations quite possible),pressing TOGA will give far too much thrust and you risk overshooting your altitude AND a possible unstable flight condition when realising and trying to recover... Keep this in mind please, I can't stress that enough. Never blindly push TOGA without being prepared for the changes in flight-path it will give.
