1. Suppressors won't do much since most of the noise from an AEG is the gearbox/motor, where it might make some difference it won't do to much.
Here's a link to a thread that modified a silencer to help muffle the sound from shooting but for a springer. If you want less noise for every shot you need to open up the gearbox and reshim, add a sorbopad, and level your motor height perfectly to lower the whining from the motor.
2. Get a MadBull V2 M4 (363mm) barrel, absolute dream. A new bucking would help but that's a topic I'm not good at for AEGs. Also there's no barrel that will shoot quieter than another.
3. As for the Bipod/Foregrip they're nice but in my experience the bipod part is a little more wobbly then a normal bipod but since your a spotter I think the combo would be nice.
