Try something simple like this

1 - Identify which recommendation configurations you believe work best with
whatever data you currently have.
2 - Run said configurations across your data, track the recommendation list
generated by each configuration.
3 - Combine the scores for items across your various recommendation lists
4 - Present results to whomever

You should probably read the quickstart guide to get familiar with how to
set the recommendation aspect of mahout up (Check the wiki and examples in
trunk)
