I was ready for the full scale rebuild back in 2008 when it became apparent that Sundin wanted go somewhere and win. Now, I'm not so sure. Kessel is an Elite goal scorer and I doubt anyone would argue that. Phanuef I see as a solid complimentary top pair defense man, hence I believe he is over paid. That said a 28 year old UFA top pair defense man coming off a 6.5m contract is going to break bank, props to Nonis for keeping the pay raise to a minimum. So we have two solid pieces both in there prime. We have some good young players in JVR,Kadri, Rielly and Gardiner if he calms down. Franson is a solid 2nd pair PP specialist and a rare RHS. Finally we have reliable goaltending in Bernier and Riemer. All this is not what we had when Sundin left, back then we had a series of overpaid players in Darcy Tucker, Brian McCabe, Pavel Kubina and Jason Blake; a group of players made for the dead puck era, and a revolving door of Knuckle busters and Horrid goaltenders. This is a totally different situation.
Now to answer your questions:
I expect Clarkson to be moved to a team such as Carolina, where they have a player signed to a horrid contract that has a better buyout than Clarkson, such as Semin who's buyout results in a 2 mil cap hit over 6 years. Carolina does not have the real $'s to buyout a player making ~$7m in salary but they do have the cap space for a player who has $1m in real salary left on his contract and the rest is bonus salary that they may or may not have to pay in full, plus they have the cap space. This is a deal I look at and expect to happen.
I also believe that the leafs pick in the 6-12 range. with that if Lawson Crouse is available I would go for him. He looked great at the WJC and brings that physical power forward game that we haven't seen since Roberts. Lupul and Bozak should be shipped out for cheaper options and picks. Keep Riemer for another season as goaltending depth is huge. Trade him at the end of next season like LAK did with Bernier. The next ~2-3 years may be as frustrating as this one but unless Kadri or Nylander has a major breakout year establishing himself as an Elite Centre in this league, gotta keep on just drafting developing, keeping cap to a minimum and retaining assets.
Another deal that I would get in on is for ROR. It would sure up the top 6 of this team and add diversity to the top 6. I personally don't feel he is leaps and bounds ahead of Kadri or Bozak, but he plays a different game from theirs and this team has too much of the same. If Gardiner is the asking price, I would go for it. At this point I think Jake has the potential to be a very good 2nd pair D but we have Percy who looks promising enough that he can replace him in the short term and Finn is another developing Dman that looks to be a bonafide NHLer.
Last point. Godla was just Godly in the WJC. He currently sits as a ~2-4th round draft pick. If he is still available when the leafs pick in the 3rd round, I would grab him and bring him over to his CHL team to develop some more. Keeps depth at the position and he's a guy who I would think could challenge Bernier for the #1 one day.
