OK I wanted CWM to do a full backup before starting anything else, I've always worked this way and I had no problems with the OSF. Secondly I read in one of the threads that if you unlock then subsequently flash CWM or Rot and Spueruser you loose your unlocking. Could have remembered wrongly as my brian is a bit scrambled.
Then install CWM as per instructions and do what you wish to do, albeit there are already some stock images in the appropriate thread. Then follow the instructions in the unlocking thread and the first part of that it to install the stock recovery so that you have access to FTM mode to go through the unlock procedure.
From there if you wish to keep to a stock image then you will need Super User installed to allow you to debrand etc. If you are going to install a custom ROM then forget SU as that is part of the ROM.
At the end of the unlock procedure you get to install CWM so that you can then decide which ROM to install.
Installing SU or CWM does nothing to compromise the unlocking of the phone.
When you have unlocked the phone then I would consider, for example, installing the Atomic ver 2.0 ROM (complete with SU) and the small patch etc as it performs so much better than the stock ROM's available,. But that would be your choice.
But read the relevant threads first and not just the stickied opening post of the unlocking procedure, for example.
