According to Dragon Ball Wiki, yes, there is one, but it is called Dragon Ball Z: Buu's Fury. It is still the third part in the trilogy, even though it doesn't have the "Legacy of Goku" title.

No, there is only Legacy of Goku 1, 2 and 3.
yes, over 9000.
Super Saiyan 3 is the last Super Saiyan level in Dragon Ball Z. Goku acquires this level when he fights with Buu. In Dragon Ball GT, Goku and Vegeta both become Super Saiyan 4, but that's after Dragon Ball Z.

No super saiyan 4 is the max Goku can transform too.
There is no super saiyan 4, its only until super saiyan 3 (Broly,Vegeta,Goku and Gotenks). There are only characters of Dragon Ball Z Kai, not Dragon Ball GT.
Best way is to play the Dragon Ball GT saga. Play against Nova Shenron as Son Goku (GT)... In the beginning of the bout, fly into as many buildings as it takes before finding a dragon ball. Most times you'll find it pretty fast. You can tell you have a DB if the symbol pops up between your health huds.
There is never going to be a Dragon-Ball z legacy of Goku 3 but there is Dragon-Ball Z Buu's Fury which is basically what happens after Dragon-Ball z legacy of Goku 2.

Well, there is the order for the Dragon Ball series: 1 - Dragon Ball (starts with Goku as a child and finishs when Goku marrys) 2 - Dragon Ball Z (starts when Gohan, Goku's son born, and finishs when Z Fighters beat Majin Buu) 3 - Dragon Ball GT (starts when Goku is training with Uub and finishs when Goku finds 7 Black Star Dragon Balls and the dragon grants his wish) 4 - Dragon Ball AF (i don't know about it but Goku there goes ssj5) P.S. As for Dragon Ball Kai, that's like Dragon Ball Z but its redrawn.
Goku.
there is no season 2 for dragon ball gt only a hero's legacy
