All system application apks are either placed under /system/app or /preload/symlink/system/app as in case of slimrom. There are only two apks that are placed under fraemwork folder (framework-res.apk and twframework-res.apk). All user installed application apks are placed under /data/app folder. To prepare CWM package, first you need to decide where you want to place files.

To begin with, use CWM package template provided in post2. just unzip template package on your desktop. As we know, in slimwizz all system apks are placed under /preload/symlink/system/app, you need to place secphone.apk and Phone_Util_Q1_EUR_OPEN.apk under same folder in package. lib files are placed under /system/lib hence libaudioflinger.so should be placed under /system/lib in package directory. /system/lib folder also have subfolder named "hw" where you need to place audio*.so.

Once done go to \META-INF\com\google\android where you will find updater-script, read it. more or less its plain english. as of now you dont have to change anything since everything is taken care there. now zip the whole folder structure so that /system is at the root of zip file. your CWM package is ready. You can flash this package using CWM recovery.

For more understanding you can unzip any rom that you downloaded and look at the files and folder structure. In case of questions/queries there are many XDA members who are willing to share what they have learnt. PM me if necessary. I will be happy to share what i understood.
