There are quite a few variants of 12.7 and 10cm guns, you would probably have to be more specific about it.

The stat used to calculate damage output is firepower and most small caliber guns would have around 1 to 3 firepower and actually does not make much of a difference. The main point of me using 10cm_Twin_High-angle_Gun_Mount is because they have anti-air stats as well as providing equipment modifiers to my ships shooting down abyssal planes. You can read more about shooting down planes during aeriel phase here.

I am not certain if there are any game viewers on phones, if there isnt you will probably have to do a bit of math on your own to calculate the Fighter Power of your fleet. Alternatively you could use online tools such as Kancolle-calc to help you count this stuff. Do take note to include the rank(>>) of your planes when using such tools.

Other than that i believe there is no debuff mechanism available at E3. Did you mean normal chipping runs to reduce the boss' hp and you are now in last-kill formation?

Like i mentioned before, do not only use torpedo planes, they do not provide fighter power. Acquiring AS(Air superiority)or AS+(air supremacy) through having sufficient Fighter Power around 200 for Easy mode AS will allow you to utilise various mechanisms such as contact, artillery spotting and reducing plane(from your side) being shotdown. All these mechanisms will give you an advantage in those battles. Read more about these mechnism on the Combat page.
