Digital BW, The Print

I just installed QTR using a 2200.  My plan is to use the Epson inks (or 
maybe
MIS black?), but otherwise have a dual purpose color/b&w printer.

I have a few really basic questions.

-1- I'm on XP and using a good old parallel printer cable to hook up
the 2200. Is this OK with QTR?

-2- I stupidly installed the Epson Photo Black, but typically print on 
EEM. I
bought the Matte Black, but haven't installed it yet. I use windows XP, but
having read of Mac issues swapping the inks, is there anything I have to 
worry
about using XP? 

-3- Also, can I save the Photo Black cartridge, and if so, should I do 
anything
to preserve it (baggie, skotch tape, etc.?)

-4- I've  been using the C86 and MIS EZ inks on EEM. Moved to the 2200 to
get some larger prints and to (hopefully) have a dual purpose color/B&W 
printer.
How should QTR results (with Epson UC inks and EEM) compare (generally
speaking) with what I've been getting. In other words, as I tweak, what 
should I
be looking for? Any known glaring differences I just should expect and
shouldn't worry about.

-5- I use PWP (PictureWindow Pro), not PS. Should I just save a
grayscale to a TIFF and use QTR GUI to print?  Are there other options
using PWP?   Does not having PS prevent me from having a satisfactory
QTR experience in any way?

-6- With the MIS EZ system, I use M-W, Y-W, C-N to get a mostly
warmish image. Is there some curve combination (if I have that lingo
right) that I can use to get approximatley the same tonality?

Very impressed with QTR's setup and what not. I'm hoping to get
some decent results without too much teeth pulling


Thanks much!
