I am a total noob at commands. I can do really simple ones like fill-replace stone to air in a specific area, but I can't figure out how to set up the code for things which require more complex logic or combined arguments. At the moment I'm trying to set up a command block to pick a random jungle wood stair block and replace it with an acacia wood stair and keep doing this until I shut it down, to try and give the roof on my large scale building a weathered look. Can somebody please explain how to code that and why all the parts are set up the way they are?

You will need to do two things:
- Firstly, there are two other parts to the
/setblockcommand that need to be present; the datavalue, and the method of handling the existing block, if any. - Secondly, the data tag at the end should just be
{Command: "testfor @p[_=1]"}, without the TileEntityData bit.
Thus, the resulting command should be along the lines of
/setblock <x> <y> <z> command_block 0 replace {Command:"testfor @p[_=1]"}
As proof, here's a shot of me using that command:
And here's the result:
The m after r=2 is unnecessary and does not search for that number of chunks (thanks @Skylinerw). By adding it, the command block ignores the radius parameters and instead searches the entire world for the player. In order to search in a radius of 2 blocks, remove the m.
Your command should look like testfor @p[x=437,y=72,z=2363,r=2].

While this isn't vanilla, I would use worldedit for this. Much simpler.
Just select the area with the worldedit wand then do:
//replace junglestair:DATAVALUE 10%acaciastair:DATAVALUE,90%junglestair:DATAVALUE
which will replace 10% of your jungle stairs with acacia stairs. You'll have to do the command once for each stair orientation though. (Replace "DATAVALUE" with the proper number for each orientation)
You'll need the clientside mod or the plugin (on a bukkit/spigot server) to do this though.
