More easily done in the big fights, such as the title defenses and the title shot itself. The awards may be randomly awarded, but by knocking out your opponent in a bigger, more hyped match you have a stronger chance of obtaining them. Either knock your opponent out or use a submission move in one of these fights to obtain the award.
As for Fight of the Night, some times you can actually hear the commentaries joke about "Fight of the night" when your exchanged in a bloody brawl. I got it when I made it to round three in a title defense against Rashad Evans. Don't go for a quick knockout or submission move.
