Kali linux for Pi can be found on this link : http://docs.kali.org/kali-on-arm/install-kali-linux-arm-raspberry-pi with instructions to follow in order to make it work on Rpi.

As far as, re sizing partition(s) is(are) concerned, you will have do it manually. You can follow this guide. It's pretty straight forward. I used it while re sizing my Ubuntu rootfs. This works for any linux distro pretty much .Link : http://elinux.org/RPi_Resize_Flash_Partitions

Edit:

One of the alternate solution could be grabbing raspi-config package from raspbian repo and install it on Kali Pi since both are debian based distros, it should work out of the box. Again, I've not tested it but it should work in theory.

Here are the steps :

1. wget http://archive.raspberrypi.org/debian/pool/main/r/raspi-config/raspi-config_20150706_all.deb
2. sudo gdebi raspi-config_20150706_all.deb

Raspi-config utility should get installed by following these steps.

Try running sudo raspi-config to check.

Hope it helps.
