    Suppose I have a Decision Trees mining model with 25 inputs.  When I use the mining model view in BIDS, it only shows me that 4 of the inputs are used in the model.  If I'm happy with this model, and setup an SSIS package to training and process this model, if over time one of the inputs no longer becomes useful in the model, will it discard that input and go to the next most useful one?

    Yes. Retraining a model (actually, a mining structure) via SSIS (or any other way) discards the old patterns and replaces them with patterns specific to the new data. It is only the metadata that stays the same (the list of columns, their content and usage and the algorithm and parameters)
