Look, making you start over is just a easy way to end a video game. In the other to games in the series, it does the same.
you use bomb-ob twice
In and around Peach's Castle. There are some hard enemies to defeat there. :)
To get the star Rank, you have to get to level 40 with Mario and Luigi. Your reward is the Excellent! Badge. To get the Final Rank for Bowser, you have to get to level 40 with Bowser. Your reward is the Intruder Fangs. They let you take two turns in a row. Hope I helped!

probably final bowsers castle
Dark Bowser

Games like the Mario & Luigi series and Paper Mario don't save after you beat the final boss. Because this games follow a storyline, you can't just go back and defeat the bosses when you feel like it. It wouldn't make sense.
to get to bowsers galaxy reactor complete Bowser's Dark Matter Plant and Obtain 60 stars when you do this you will be asked if you want to fly to the center of the universe say yes to enter the level To unlock Grand Finale Galaxy get all 120 stars with mario, then beat the final boss to unlock Luigi, then get all 120 stars with luigi, then beat the final boss again, after the credits have rolled you will get a message say you unlocked grand finale galaxy
Pretty much all of the bosses. (correct me if I am wrong) Bowser could be FIGHTING the final boss, too. (ex. Mario and Luigi, Bowser's Inside Story, etc.)
