Well, I'd personally punt any of them for at least one round at We-Ko-Pa (
http://wekopa.com/) - I'd actually drop two of them and play both courses out there, maybe on the same day for logistical reasons. The courses have fairly distinct personalities so it wouldn't be like playing the same track twice. Simply put, those courses imo are better than anything on your list and are almost certainly a little cheaper.
BUT, since people like to play where the pros play - TPC, Grayhawk - and Troon North has a certain aura to it, it's hard to talk you into dropping any of those if you have your heart set on them.
That said, the order I'd drop would be Troon North Monument, Grayhawk, TPC, Troon North Pinnacle. Pinnacle is the stronger of the two courses so worth keeping. TPC is a nice change from all the other desert courses you have scheduled and it is fun to play 16 and all the other holes you see on TV. Grayhawk is better than Monument, which I suggest getting rid of first because it has some goofy holes and you'd be better off playing elsewhere.
Also, as price doesn't appear to be an object then look into either the Boulders (

http://www.quinterogolf.com/), which is straight down Carefree Highway from where you are staying and spectacular - best par-3s in the state.
