The filter that comes with the SRI is pre-treated so no worries there...
As to how often, it depends where you drive and how much you drive. In normal everyday driving I'd say twice a year should cover it unless you drive a lot of KM or in extremely dusty conditions...
As to the bottom piece, you can either remove it or what was done in my case was a cap was put on it to prevent any crap from hitting the bottom facing part of the filter..
