| Tom, is this the first roots to come from the recently mature growth? If so, now is the time to repot. If you are only seeing roots growing from older roots, it may not be too good to repot now, but you will just have to wait and see how things go. If you did not remove 100% (or 98%?) of the old bark you are probably going to have to keep an eye on the older section and be prepared to repot again in a year or so. If you removed all the old mix, you should be good for about 3 years.
I would say that one should never remove all roots unless one lived in a very tropical climate, and even if I did, I wouldn't do that.
Wieb, you don't ever want to have dissimilar mixes in different parts of a pot. You'll never get the watering right for both at the same time. A few chunks of rock here and there won't hurt things, just be sure you are checking the moisture level in the bark, not in a denser part of the rocks.
