While I've been playing for many years, I'm a lot newer to the intricacies of recording. Your mention of the differences between mod wheel and expression dynamics - as embarrassed as I am to admit it - is something I had no clue about.
My main controlled is a Yamaha Motif ES8. I use the second switch pedal to switch velocity xfading on and off. For strings I usually use the mod wheel as the velocity controller. For brass I use a Yamaha breath controller. I'm currently using only one continuous pedal and have it set for expression (controller 11 is just volume on the MIDI channel but technically not the same thing as MIDI volume, which is controller 7). For long notes I try to perform with both the expression pedal and velocity cross fade as I record MIDI into Logic. I almost always end up editing both of the continuous controllers in Logic.
There are two demos on YouTube if you Google "vienna instruments velocity crossfade video demo".
This video shows how to set up velocity xfade at around 3:50.

Beat Kaufmann has some excellent tutorials. There is some info here on velocity xfade.

It takes practice but the result is worth the effort. In your case, i would highly recommend a breath controller to shape the intensity of the sound (velocity layers) while using a foot controller for MIDI "expression" (i.e., loudness). So to summarize, I would get a keyboard with sustain pedal + extra foot switch input, one or two continuous controller pedals (one for expression), both pitch and mod wheels and input for a breath controller.
