The honest answer, Bob, is that I'm not sure. I figure for no more time than it takes, I like to have the services started in the order Zimbra is used to having them started, in case a change of pid or something screws it up. Belt & suspenders, I suspect, but I'm that way. . .

I would recommend you enable the RBLs to increase the spam detection. Turning them on will catch a great deal of the most egregious junk, bayes or no. The clearest documentation of how to do that is in the Zimbra
Administrators' Guide, page 38. Lowering the spam threshold from the default 33% to 29% helped me too (GUI, Global Settings, AS/AV); it changes the raw score that defines a message as spam. . .for me the default of 6.6 points wasn't enough with the scores of the RBLs, but 29% lowered it to 5.8 which, for me, has not increased false positives but significantly lowered false negatives.
This wiki article will also give you a variety of useful pointers.
None of this changes your Bayesian problem. You still want to get that fixed, I understand, but a lot of these other fixes will also help. The best Bayesian filter in the world isn't enough to handle the spam problem on its own either.
I see from the announcements section that 4.5.9 has been released. 4.5.6 didn't have trouble with Bayes at least in my experience, and I installed it on Ubuntu LTS, so that shouldn't be the cause of your problems; however, there is a chance that doing the upgrade would fix whatever's broken on your filtering. It's worth a shot. Beyond that, I'm afraid I have to defer to the real gurus!
Good luck,
Dan
