Digital BW, The Print

I have been following this forum a few weeks and find myself confused 
about options and capabilities.  I have a 1280 with which I have gone 
through a lot of stuff to get good color prints.  Now I want to do 
B&W too.  My thought was that I would buy a 2200 and use that for my 
color work and use my 1280 as a B&W printer.  However, the snippets 
of information I picked up here about ImagePrint have me wondering if 
this is really necessary.  So here are my questions:

1.  Could I buy the 2200 and the light version of ImagePrint and use 
the 2200 for both color and B&W?

2.  If the answer to 1 is yes. Would I be restricted to Epson's inks 
or would it be possible to use oem inks and cartridges?

3.  Would there be some restriction w.r.t. papers?  (I am assuming 
that if there are limitiations (w.r.t. #2 and #3) these will be 
removed as more vendors move to support this printer.)

4.  Finally, I notice that Kodak has recently entered the printer 
market with dye-sub printer.  How are these for B&W?

Finally I want to say that, although sometimes the posts in this 
forum include a lot of extraneous stuff for someone who gets only the 
digests, DigitalBlackandWhiteThePrint is one of the most vital and 
information-rich forums I have seen on the internet.  It is a 
wonderful resource and I appreciate this community and the generous 
sharing of its collective knowledge.

Thanks,
