Edit: I just re-read your post and see you've already done this. I tried it and when I brought in a new view it had those settings, but I didn't try to save and re-open. If those settings aren't sticking for you you should probably contact your VAR, unless someone else has any ideas.
Select the options indicated below at Tools > Options > System Options. You said "we", so I assume there are multiple users at your work. If so, they will each need to do this.
The system options on those display settings are on NEW view creation, not switching between. My guess is that when you switch from wireframe to shaded it changes to draft to save on regen time by default. I doubt this is a setting you can adjust. Best bet is submit an Enhancement request, but you may be on your own on this one.
