Hi.

1.
You have several options to acheive something like this. You just have to find something that suits your needs.
There is also several post about this topic on devzone. You might find a lot of useful information from a quick search.
I suggest that you take a look at the Heartbeat message.
Quote BT SIG;
"Nodes can be configured to send a message known as a Heartbeat message, periodically. The purpose of the Heartbeat message is to indicate to other nodes that the node sending the Heartbeat message is still active and to allow its distance from the recipient to be determined, in terms of the number of hops needed to deliver the Heartbeat message."

Also take a look at this previous post.

Yes, it should be possible to change this on the fly.
Where do you change the TX-power in your code?

Best regards,
