Digital BW, The Print

Hi all,
I'm a relative newcomer, having just received my first batch of mis vm inks 
that I'm running on a 1280.  I had a couple or three initial questions that 
I didnt find ready answers for.

1)Are there any recommended gloss or semi gloss papers?
2)What are some guidlines for acceptable dpi.  Scanning from 35mm negatives 
at 1600 dpi, what's a reasonable enlargement size to hope for?
3)I noticed on the mis site, it recommends only using brand new cartridges 
if you swap back and forth between epson and mis inksets(or mis and mis 
inksets) or the printer could lose prime.  Has anybody actually had 
problems with this?

Any information would be greatly appreciated...

thanks

-david
