I'm planing to use CFL light bulbs because Easy to find and easy to use I find.
What's the recommended watts I need for veg stage and flowering stage? With CFL bulbs.

With cfls, atleast a minimum of 50w sq.ft
Examples with actual wattage draw (not equivalent)
2x2 - 200w
2x3 - 300w
3x3 - 450w
4x4 - 800w
Seriously, i would rather use these

Are you using CFL?

No you can start off seedlings under cfls but you won't get much of a yield flowering or even vegging for longer than a few weeks under those. I recommend nothing less than a 400w or LED equivalent for mid veg through bloom phase.

A plant will only grow so big before it runs out of light, i wouldn't use 160w of cfl in a space any bigger than 2 sq. Ft. (1x2).
Keep in mind penetration, efficiency & heat is terrible with cfls and will give you nothing like the lights posted above.

Dude if you are dead set on using screw in bulbs use led bulbs they are way better and actually grow really nice bud.

Of course u can do it but its not optimal for cfl. If u want to use cfl for vegg optimal will be 300 actual watts and up.
