Rollsman44, you seem to have your priorities well sorted out, and have picked an excellent tool to use to meet those priorities.
I used the H3D-II/31 for many years, and found it to be a versatile tool that is capable beyond what many think it is. Some of my best work was done with that specific camera, and when I moved to the next model I really didn't gain all that much in real world terms … especially when working with lighting.
Sticking with a camera for some time has many advantages because you come to learn it well enough to make it sing in your hands … much like a musical instrument. The more you use it the better and faster you get at it.
The Hasselblad website has many learning tools to get more out of your camera than the manual can provide. In particular, the HTV section has video tutorials and demonstrations worth exploring.

Phocus is essential to have on your computer even if you only use it for a few things that it does well. At least two things are essential … using it to upgrade firmware for the camera, viewfinder, and lenses … the second essential use is for tethered shooting to a computer via the firewire 800/800 or FW800/400 tether cords that should have come with the camera.
My opinion regarding Phocus verses Lightroom is based on applications … how the camera is being used.
Hasselblad provided Adobe with all the profiles for DAC lens corrections and gave them the camera color profile. So, for many applications LR is just fine … especially ones where the features of LR outweigh some of the more refined color engine tools found in Phocus. If you are already really good with LR, you may find it works well most of the time.
What I like about LR is that it is nondestructive, retaining the RAW file and history of corrections, and LR's cataloging features. I also like that LR allows use of other software without leaving the LR catalog. So, I used LR for most event work like weddings, and larger corporate or commercial jobs with a lot of files to manage.
When working in the studio, I almost always shot tethered to Phocus. Generally this involved less volume shoots where most shots were a progression to the final approved image. Phocus does provide some very innovative color tools to refine images requiring more color correct rendering. I particularly like the Phocus color wheel for isolating a specific hue and adjusting it without altering other colors. I wish LR had such a feature that was this refined and sensitive.
Hope this helps if only a little, and best of luck with your H3D-II/31!
