New Pipe Smoker With A Question? Ask an Old Fart

OK, I just finished a NST with Slow Triathlete (thanks again!) and now I have a couple of questions...

1) Storage - can I store different pipe tobacco together? I don't have any fancy jars so I was going to use an old herf-a-dor and just leave them in their bags...will that mess up the flavors?

2) Humidity - I have seen posts regarding re-humidifying dry tobacco, but should I keep some humidity control in the container with them, like cigars?

3) Aging - does pipe tobacco age (get better, change profile, etc.) like a cigar?

I bow to your wisdom and thank the mighty fog's of the pipe in advance
