A question about rapid fire for modded controller help?

I'm looking to buy a modded ps3 controller from rapid modz. There are a few add ons you can choose, such as
Akimbo
Auto burst
Zombie mode
Jitter
Ect.
One thing I want to know is what those things mean, and the main thing is do I need them for rapid fire. I think I'm aware that one of these things changes single shot weapons to burst weapons, and another changes burst weapons to fully auto, but I want all weapons on the call of duty game to be fully automatic. So does that mean if I had the one that changes burst fire weapons into fully auto, would I need the one that changes single shot weapons to burst fire first in order to become fully auto? Sorry if my question sounds confusing but I am very confused on This topic too,
