I'll give you some direct answers, then my interpretations of same:
1. Beast companions always start with an Int of 6. Which is pretty smart, for an animal, actually.
2. There's no such thing listed.
Now, my interpretation:
I wouldn't give Ranges a magical ability to communicate with, and to receive communication with their beasts. They're martial characters, and while they can exhibit "magical" or almost magical abilities, their abilities are fundamentally, except when proven otherwise, of mundane, not magical origin.
However, if one examines the abilities and relationship of a Ranger and his or her beast, there are a few things of note:
1. The ranger and beast can act as the same person--there's no way to cut off their ability to communicate when they're together. Therefore, I'd assume they have a sophisticated set of signals going back and forth and let the ranger know what the beast sees/hears as long as the ranger can see the beast.
2. The ranger's player can control the beast almost without limitation as long as the ranger is not present. The beast is quite capable of acting intelligently (wthin Int 6, but note that's only a -1 relative to a dumb human PC) even without the Ranger directing it. As such, one must take as written that the limitation on the beast only acting when the Ranger commands it is an abstraction (take as you like whether it's an abstraction of the Ranger's players not getting to break the game vs the load of coordinating their actions); really, the Ranger acts and the Beast acts, but each is entirely capable of acting on their own information.
So even if one rules that for one reason or another, the beast is incapable of communicating a crucial bit of info they learn (eg, that there's a bad guy creeping through the dark room), I'd argue that the -beast- should still be able to act on that info, using the Ranger's actions to do it. Normally, one would handle this by out and out saying (since the Ranger's player typically plays the beast as well; if you're deviating from that you change things around a bit) that the beast notices something and the ranger doesn't, and does the player want to have the beast act, and trusting the player to keep character knowledge separate for the brief period where this is relevant.
In terms of scouting reports...well, it's got a 6 Int and is highly well trained; anything it understood it can probably relay, but there is some leeway here.
