Missing and duplicate entries in the calendar

Question

I'm a long time (1997) Palm user who's moved to a BB 8330 last month. I can't seem to get calendar syncing to work correctly. In some instances, I am missing items on Outlook. I often have duplicate entries on the handheld. I've searched the forums and there seem to be similar issues and the solutions appear to be around Service Books, but I'm not confident I have a clue how not to lose lots of info.I also cannot seem to find information that explains the relationship between email addresses & calendar (I don't see why there should be any!!!)
Scenario (trying to answer up front the questions from other forum posts):
I am using Outlook on my home computer to manage my personal calendar. I do not have an email account associated with Outlook.I have set up 2-way sync with Outlook for calendar, tasks & contacts
My work uses Lotus Notes. I have set up one sync to the handheld only from the Lotus Notes calendar
The only email account configured on the BB is a gmail account (which is not associated with either calendar). I originally set this up via the wizard, then removed it, but added it back (under Email settings) when I discovered I couldn't send email from the Address book without it. I actually prefer google mobile for email management since it modifies the server state as well. Not sure if the add/remove/add sequence has somehow messed up the calendar?
I have checked under Calendar > Options and two calendars appear. Based on the color associations it appears that Device Default is associated with Outlook personal calendar & my gmail account is associated with the Lotus Notes calendar entries. As far as I know I did not create these associations. 
Checking under Options > Advanced Options > Default Services, I see CICAL & CMIME entry and those are both the gmail account.
Checking under Options > Advanced Options > Service Book, I see only one CICAL & CMIME entry and those are both the gmail account.
Separately, I do have a couple of mobile apps to read email (gmail- same acct - and yahoo), but those appear to not integrate into the BB apps directly. 
Everytime I sync with Outlook, I end up with lots of duplicate entries on the handheld. I have also noticed that I am missing entries that are on the handheld, but are not on Outlook (in one very odd case, the entry was created on Outlook and now only exists on the handheld). I may have deleted duplicate entries related to the missing items at one time... I can't be sure about that. I believe I currently have a complete calendar on the handheld, but not 100% confident I have a good calendar anywhere. 
And as an aside, have to say I'm really bummed that I have lost easy access all my Palm historical data. It appears BB will not bring in old calendar data by design (found that in some BB documentation on their site).  Now that I will not keep up with Palm upgrades, at some point I will lose access to that data. Sigh. 
Any, all help appreciated.

Hello...correction:

Ok. In that case, try this. (That worked for me when I had similar problem. Ignore if you already tried this)
1) Turn off the phone
2) Remove the battary and place it again
3) Restart your phone
Have the BB ON (e.g., something showing on the display, the HomeScreen would be fine) when you remove the battery. That is the cleanest hard reboot method.
Good luck!
