Looking for RAM expansion of my ATRIX2- Android

[BKB999]

Hi,
I am from India. I am using Motorola ATRIX 2 with 4.0.4 ver android. I want to root my mobile since my RAM is getting fully utilized by the applications and so the phone becomes slow often. Please anyone can suggest which is the best software to root my phone and to increase my RAM using external SD card.
Whether there is any problem with expanding the RAM to external memory? If yes please suggest some alternative.

Thanks
