I also had a list of what I wanted originally after all the research I did and the list is pretty much out the window. 
Anywho, as far as the roos go, in my experience the Easter egger roo I had was really great.  He was handled everyday by a 6 year old until we re-homed him.  Apparently, he is still super nice to the new humans he interacts with.  So, the key is handle when wee.  Even then, there is no guarantee that the roo will always have a sunny disposition.
I'm in Florida as well and started on this chicken adventure in suburbia last November.  I found someone who had all the types of chickens I wanted and then 2 were roos, one was a cannibal and, whoops, that's a Minorca not an Australorp, and so on and so on.    My black star is super smart, my blue plymouth rock is also smart (for chickens).  I really like the EEs I have now.  I also decided that, like any animal, try for the ones with the best descriptions for your personal needs but don't get too upset when they don't line up perfectly to that description.  The mutts I have are really great and since I'm not concerned with breeding or showing them, that works for me.  Obviously, if you are into breeding and showing you would want to start with super awesome stock of which I am not a reliable source, but as far as egg laying, my random mix of hens are really starting to rock it.  And so I learned that what actually occurred at my house is attributed to chicken math, Start with 2 add 8, take out the obvious roos=8, subtract one cannibal, add 4 because you just can't have *one* silkie and *one* orpington, oh, that's not an orpington thats a golden comet male take away 1 add 2 (of course), darnit a couple just weren't good at living, take away 3 add 4, can't say no to the 4-H hatching project, add 4, take away 1 non-survivor, cockadoodle! Goodbye -2 etc etc..We're at a manageable 14 now...now. 
What I'm trying to say is this: start with your list and have lots of fun; all of the strains you have looked into look great for what you describe (I am so not an authority on anything but I read a lot) You will find all sorts of chickens to be incredibly easy to come by very soon.  There is a Florida Thread on here somewhere and there are swaps announced as well and there are definitely some breeders around with eggs.  Naked necks are apparently good Florida chickens (gotta put that on the list)  Ours live in coop/run combos under a giant live oak so they are always shaded with dappled sunlight and get to take walks around the yard throughout the week.  It's always cooler under the tree.
