Not out of the box, you will have to modify the code to output the data 
somehow.

...for example like this.

Drop them in the decode MAC block, or use Wireshark to filter. (Of 
course you cannot filter based on the MAC address at the channel 
equalizer. If you want CSI from a certain MAC address only, you will 
have to annotate the CSI (-> stream tags) and print it once the frame 
was decoded and the MAC matched.)

You can configure the antenna in the USRP source block.

Yes.
