Rig For Red
The term "Rig for Red" is actually an older term, since most submarines today use broadband Blue lighting for night operations. Many spaces on older boats still have Red lighting, though.
"Rig for Red" is normally a command used in the Control Room. It is normally used when the boat is going to be surfacing or coming to Periscope Depth at night. The purpose is to give the lookouts and the officer designated to head to the bridge upon surfacing a chance for their eyes to adjust to darkness, or the OOD the same thing before looking through the Periscope. However, with the change to Blue, often times Red glasses are also used to provide the same effect and then Control is changed when the command is given to surface or come to PD.

In the context of Qs post I would speculate that Q team is surveying the battlefield and preparing for an attack run.

Silent Running
The term "silent running" is sometimes used to describe the standard operating procedure used by the crew on a submarine when they wish to become as undetectable as possible. It involves the observation of "noise discipline," minimizing noises which could alert other ship traffic to the presence of the submarine. Many people have romanticized the concept of silent running, thanks to war films featuring tense-jawed submarine captains and nervous crew.
Like a Hunting Cat, Prowl Silently, Go Silent and Still, then Pounce
This is another attack run directive to all. Int he context of Q it is an instruction and notice that Radio and Comms are reduced to as minimal as possible. This is done so as to deprive the enemy of any signals or indications as to attack plans or targets. Also, the DS are not the only ones with sleepers. This is letting them know that they must maintain maximum stealth in preparation for activation/action.
