For BQ29330, if the protection and cell balancing funtion fails does that affect the monitoring function. Also, any details ( documents , white papers) on I2C interface and cell balancing would be appreciated. Board designs etc...

In my opinion, if anything in the IC fails, then all functions should be suspected. Thats why a typical battery management system follows IEEE1625 and provides redundant protection.

We have plenty of app notes on cell balancing and board design on TI.com at, for example: http://focus.ti.com/docs/prod/folders/print/bq20z90.html#applicationnotes

But, if you are considering use of the bq29330 without a matching fuel gauge, there is very little collateral available other than its datasheet.
