As far as 1) it's a few miles up hill. The way to get to the current flow would be the trail at the end of S. Glenwood road, but it's closed. It's about 2 hours fast hiking on a clear day to the forest clearing where you can see Pu'u O'o and probably 30+ more minutes to the new fissures.
As for 2) it can be either, but depends on height of the previous flow. It will just go around it until it builds up and covers it. Look at the cliffs from Kehena and you can see the various layers of a'a and pahoehoe over the years.
