I don't think anyone's mentioned this, but another tool that is very
helpful when soft-proofing is the gamut warning in Photoshop. It will
save you from the frustration of trying to correct something that's
either not attainable on the or you can't see on your monitor,
particularly if you've got an old or not-so-great monitor.
I would also like to say how refreshing it is to hear from a 4-color
printer who is pursuing a color-managed workflow, instead of rejecting
it out of hand as many do.

In that case, I suggest supplying your clients with .csf files for
the adobe apps, and include your proofer profile.
Way more important than the choice of RGB space (because apart from
the huge ones that you don't want to put in the hands of the
clueless, they all clip some printable colors and all contain plenty
of unprintable ones), is the ability to soft-proof to the
destination. Supplying your proofer profile as the CMYK working
space, and telling your clients to work with CMYK simulation turned
on, is going to do a lot more in terms of avoiding surprises than
choosing any particular RGB working space, because the user can see
the box of crayons they have to play with.
Supplying a .csf that has "Preserve Embedded Profiles" set as the RGB
policy would also make it a ot less likely that you receive untagged
or mistagged RGB.
My $0.02.
