Not positive about the "and here" sections.... But the tabs are actual images pulled from framework-res.apk. they are not in the phone apps. Those tabs are shown thru settings, phone, calculator and other apps. Compare the images in your framework-res.apk drawable-xhdpi or drawable-xxhdpi folders.
If you look at the theme linked in my Sig, you'll see I have the icons replaced with PCB images..... You can compare my framework from the theme to see where your images are... And what they are named.
Edit: I should add I'm on the s3 running kitkat 4.4.2
