Kevie has identified the things that needs to change, I just hope he knows how to make the changes happen.
As for players being moved on, it's not just a matter of getting rid of the shitters, it's about getting rid of people where we won't need to pay a chunk of their salary cap. With that being said, Lodge and Offa are probably two people that could probably find another club paying their full salary or at least very close to it. Getting rid of someone like bird isn't going to help much as we will probably be paying most of his salary anyway, and there probably aren't many players out there better than bird at $400k (assuming he can play a game).
Based on this, the big contract players who are more likely to be able to find a role somewhere else are probably Offa and lodge, and then behind that probably Isaako, Macca, TPJ, Oates and then you have Milford / Bird but most clubs won't take them anywhere near their asking price.
Then after all of that you need to look at who we could bring in. Now things always change and players get released etc. But there aren't many that truly stand out for us to target. I'd argue we need 1 or 2 hard forwards and then a quality fullback. I still think a Milford and Dearden halves combo could be very strong.
