For #2 you might be able to get away with the following: https://cwiki.apache.org/confluence/display/solr/The+Term+Vector+Component
The Term Vector component can return offsets and positions. Not sure how useful they would be to you, but at least is a starting point. I'm assuming this requires only termVecotrs and termPositions and won't require stored to be true.
