*edit*: i think i might have to re-watch later xD
The people knew what Rick looked like because someone saw him in the house, if you remember the episode when Rick encountered those guys there was a scene in the bedroom. Rick is trapped under the bed. Two guys fight over the bed. One guy puts the other into a choke hold on the floor. That one guy looks under the bed and sees Rick. That guy wasn't choked to death. He didn't die and Joe pointed him out saying pretty much "he saw the guy who killed him, we know his face". And they knew that Rick was undoubtedly the one who killed their pal in the bathroom. In an earlier episode they revealed that Joe and his gang were tracking Rick and know that he's on the railroads. Much like how Daryl tracks people.
How they were able to identify Rick in the dark? I don't know. I can't remember now if there was a fire going anywhere. I don't think there was. I guess all they had was the light from the moon. Perhaps they made an assumption that it had to be the guy since it was three people and they were looking for three. But it is strange that they were able to find, identify, and jump them effectively in the dark.
I rewatched the episode and paused to see the names on the floor. None of them had familiar names. definitely nothing that even looked like "Beth Greene" or anyone elses name that we would know. Some just had names, a few had names and a number written beside them. Several had little items, perhaps belongings, right beside the name. Like dolls, toys, a guitar, and flowers. With how it is arranged, my guess is this room is a cemetery or, perhaps a better fit, a memorial room for their dead. Where people can pay respects to the fallen.
As for what was on the wall, there were things like "never trust", "us first, always", and "never again".
Last week it showed Glenn, Maggie, Abraham and all the rest arriving in Terminus. They were welcomed and the episode ended. It doesn't show, but it is safe to assume that the Glenn group either found out that Terminus is bad and were unable to escape, or the Terminus people jumped them while they had their guard down and they were thrown into the railcar. Pretty much they were caught by Terminus and imprisoned just like Rick, Michonne, Daryl and Carl.
