With regards to the point about Carroll's style of play and how we use him, it's up to the other players in the side to adapt to him and not just use him as an out ball all the time. When I watched him at Newcastle he was a lot quicker than some gave him credit for and we haven't really see him at full tilt yet for us due to injury. Given time he'll definitely fit into our image and style of play. People need to remember that for ages we played with a striker who hardly contributed anything to our play unless he was scoring in Torres.
Here is a really interesting article that the King wrote last season before Newcastle's game against Sunderland: the match Newcastle won 5-1 and Bramble was sent off for hauling down Carroll.

Now the bit about floated crosses goes a large way to explaining Kenny's purchase of Henderson as this is how he likes to cross a lot of the time. Barton did it well to great effect with the likes of Nolan running off Carroll to pick up the second balls. After Carroll left, Nolan's goals dried up completely. In our set up you can certainly see the likes of Kuyt, Suarez and Gerrard when he comes back benefiting from this.
There is also an excellent read here with regards to Carroll.
