Most of your equipment will do well with colro management, though the RIPs
will have to be experimented with one at a time...

Move up to InDesign 1.5 (2.0 when it ships) and it will simplify your color
management considerably. It may be a bit more of a challenge for a few other
functions, however... which should be improved by v2.

This will all work fine, these devices both take ICC output profiles fine for
RGB images. Prepress proofing of images from Photoshop 6 should work well
with them too, once you build custom profiles. The 2500 has its issues, but
it takes profiles well...

Different workfows are possible...

Any that have a popdown list for an ICC or ColorSync profile. Whether they do
press emulation proofing is also a matter of what functions the RIP offers,
though it can be done in advance with Photoshop (for images only) or a
software color server (whole document layouts).

The DTP41 with the UV filter and a good software package will build excellent
profiles for a wide range of output.

Yes the DTP92 will out perform the more generalized and much older ColorTron.
So will the much less expensive ColorVision Monitor Spyder...

I'd look at ColorVision's Monitor Spyder/PhotoCal combo, and their
ProfllerPRO, unless money is absolutely no problem. You could also consider
the SpectroCam instead of the DTP41 if you were looking for further savings.
Or go for the big budget choices, if the budget allows; they are convenient,
just much more expensive.

AdobeRGB shoud do for just about any work.

The monitor is a way to see what you are doing, and preview gamut clipping
etc... in case you want to make adjustments. It also saves wasted prints when
issues can be seen on screen first.

management works in a 2000 OS?
ICM2 in Win98SE, ME and 2000 has some bugs and issues, but does basicly the
same type of OS level color management as ColorSync. You really only need it
for building profiles, easpecially monitor profiles, most everything else is
done at the application level instead.
It sounds like you might be best off getting some consultation assistance
rather that just jumping into this whole process blind.
