Yep, all of that. Plus, he made us again look like an actual football club rather than the remnants of a circus that had largely moved on by the end of 80s. He got rid of the Swanettes (the Cheerleaders stationed at the Bradman Stand end), along with that intensely annoying song they used to play after every Swans goal at the SCG. I've recently found myself thinking about how much the re-introduction of post-goal music must have irritated him.... but I digress.
There's a case for saying he was the most important of those who arrived at the club in the 90s, i.e. more important than Lockett and Roos, partly since those two probably don't come to Sydney had Barassi not been there first.
