You need to include more details. Such as the MAH rating of your pack.

1) it doesnt matter it's a metal tube. Some companies claim they do extra milling or it's extra "strong" or "ribbed for your pleasure".

2) Long story short, It depends on the brand of drop in you buy, and if you get a lemon from the factory.

3. We need more information, such as the spring you are pulling.
I run a 35C 2200 mah 11.1 lipo (77amps CDR ~150burst) battery in my gun and it's "sufficient". If you are happy with your ROF, then leave it alone. If you feel you need to do something go to 7.4v ~20-30CDR lipo.

As for the gear grinding, it might be shimming and motor height. In which case open it up, replace the gears with something like a Guarder Infinite Torque or Standard gearset and shim it right, then when it's all put together test it and adjust motor height accordingly to get the best "whirring" sound.

You don't need to buy a new set of gears. If it's making that much noise, open, inspect the gears carefully and the gearbox shell and bearings, shim (make sure your bearings/bushings are properly seated), regrease, break-in, and repeat until you are happy.

And please don't buy guarder.
