Normalising won't help you, at all. If you want to fix the volume between tracks then you have to get dirty with some EQing and stuff. You can still do it in Soundforge but it's much more tedious as you have to change it, come out and listen to the transition which loses your makrer and if it isn't right then set it all up again. Which is where Ableton comes into it as you can just loop the transition to get the volume right then sort it on the other side.
