I’ll take the liberty to answer some to which there’s already info available.
Yes, you can pick up the weapons, but they’ll only have a small amount of ammo left.
We know that mediums and heavies can carry the bigger guns. Will certain attachments or attachments in general add weight so that a gun with a ton of additions will be too heavy to use?
No, the only restrictions are the slots on the weapon. Note that each add-on comes with it’s own negative stats to balance things out. A weapon with lots of additions isn’t necessarily better than one without any add-ons at all.
We know the GL is a heavy weapon is it also an attachment? I have heard some claim it is.
The automated GL is a heavy weapon, there also seems to be a light grenade launcher for medium bodies. I’m also pretty sure a grenade launcher can be an attachment (from an interview)
