Well you could do as the disk trends graphs, graphing by percent used. 
Percents won't help you with your other 2 questions, since with them I would 
assume you would want the amount used. You could have 2 data stats in your 
RRDs %Used & Used. Then define different graphs to used each stat for the 
different purposes.

As to your other 2 questions, I have no past experience to pull from for this. 
I would think it is possible, would just need to figure out the dynamics to 
do this within rrdtool, then apply that to hobbit's graph definition.
