1. The YJ team might not know about the Reach now, but they will know about them by the events of "True Colors". That's what I mean about them knowing about the Light's alliance with the Reach.

2. It doesn't take a long process to form a partnership with somebody in the criminal universe. You meet them, you make a deal and bam, you're partners. I'm pretty sure that what Lex was doing was signing documents to cover up Lexcorp's involvement in the invasion and to give the Reach access to certain things.
