Question About LinuxDeploy and Kali Linux

Hello, i need to install Kali Linux on my rooted android phone. I will install it to my 8gb SD Card. And here is my question:

Is 8gb enough for Kali Linux and all hacking tools? Do i need to install Kali meta packages? And if i need to wich one? And last wich is the correct way using LinuxDeploy - in the setting choose partition or choose mountpoint? I will installing on ext2 partition.

This are meta packeges that i found on Kali's website. So do i need it?

Sorry for my bad English, hope you understand my questions.
