Digital BW, The Print

After following a recommendation about the Ilford Smooth Pearl paper, I have made
some decent b/w prints. However, they are not truly b/w. They have a very slight 
sepia/brownish tone.

Is it possible to get excellent b/w prints from the standard Ultrachrome inkset? I 
admire and respect all of the customization techniques, ie Paul's curves and UT or 
Quad inks, which I'm not familiar with, but why can't I trust my own photoshop levels 
and curves with the standard inks and get some good results?

What's the point of borderless printing or minimized margins if the print quality 
stinks at the edge of the image (at least on a portrait orientation).

What is the best paper to use to get the equivalent of a nice fiber print? The Velvet 
Fine Art is not smooth like a traditional fiber.

Thanks,
