if you know C++ reading Java will be pretty straightforward.

1A It is always the second
1B SecureRandom in the Java library is used for the random numbers.
You might be better off getting a copy of the MultiBit code and reading through it for the implementation details - I don't know your programming background but the class names and comments tell most of the story.

ok...so always address number 2 no matter what....
I will read the code, i have coded C++ with open GL (a collision engine...my dream program), and other stuff...but that was years ago so I am sorta rusty
thanks

Hi Jubalix,
To answer your questions in order:
[1] If there is a single address in the wallet, it is used as the change address. If there are two or more addresses in the wallet the _second_ one is used. (This was added so that when people do a private key import, one of their addresses is used as change).
[2] The unspent transaction outputs are chosen by age so you cannot choose a specific output to use.
[3] - answered in [1]
[4] The change address is not deterministic no. All the private keys in MultiBit are randomly generated.
[5] There is no keypool
[6], [7], [8] What is in all the files and directories is covered in detail in the help here:

Thanks for very good answers. Two other thing
[1A] if I have say 5 addresses is the 5 th address used as the change address, so in general terms the 'nth' address is always the change address?
[1B] What is the rand number/gen system for keys?

I am seeking a current update or official resource on
[1] the mechanism of the change address and
[2] how to choose which address payment comes from
[3] Which address is the change address
[4] are addresses deterministic, are they planned to be in the future?
[5] is the a key pool (hidden until exported)
[6] what are in the folders
key backup
rolling backup
wallet backup
wallet unec backup
[7] what are in the files .info, .key and . wallet
[8] in relation to [6] and [7] Does this get rewritten after I encrypt, and are the files writen over so the prior version could not be recovered from my HD or do I have to copy these encrypted files to USB and security wipe HD to be sure
