Wade should stay with the Heat regardless. He's not going to get the same money anywhere else, and he's basically a Heat lifer. His trade value is much lower right now than it has ever been.
Assuming that Bosh doesn't stay with the Heat after that...
If Lebron goes to Houston Bosh should go to Chicago. Bosh would add some scoring punch and make Chicago the favorites in the Eastern conference with Lebron out of the picture.
If Lebron goes to Chicago, Bosh should go to Houston. Bosh's game fits very nicely with Dwight (stretch 4 that can also post up) especially with Dwight handling rim protection and primary rebounding duties.
And if Lebron goes to Cleveland, then it's pretty much a toss up between Houston and Chicago depending on Bosh's preference.
J.R. Smith: "They were pretty much scoring at will. Especially my guy. I don't know what the hell I was doing on defense."
Raymond Felton : "The play was give the ball to Melo."
