The obvious solution is to buy Voice Command
Sorry, he's going to have to wait for a kitchen (there are a couple of 6800 kitchen's out there - they're not as friendly as the Apache kitchen, but as soon as a stable ROM is available we'll release an official PPCGeeks kitchen).
I can't imagine what your problem is with wireless sync, given that it worked fine w/ activesync on original Helmi ROM. The most likely cause I can come up with is that it doesn't work w/ WM5 AKU 3.5 or later (file format changed), but that would invalidate the original Helmi ROM too. I did note that you let the customizations run w/ the original ROM, so it's possible that some other carrier app installation is responsible for it working. Try manually installing the extrom cabs in the order they autorun, and see if it works for you. Letting the extrom cabs run is a terrible thing to do since they're designed for a different version of WM - so I suggest a hard reset afterwords.
