The web service bit won't work without Axis but yes I think the rest does. The Axis .jars should be added into lib/axis as I recall. I believe the build file prompts you to do this? at least my build file does. I don't have it in front of me.
You hit on an interesting feature of the slope-one recommender used in the demo. It does have this odd tendency to produce similar recommendations for relatively dense data sets. I haven't really thought it through or discussed with the creator of this algorithm but I should. Top-rated items independent of user -- yes this could be added fairly easily. It is not really part of a recommender API but something computable from the data. It... may or may not really explain the recommendations in general. It *shouldn't*. In the case of slope-one it sort of does but that is not so desirable. The explanation is kind of algorithm-specific. For example for user-based recommenders the explanation relies on the user neighborhoods that were computed. For slope-one it kind of depends on item-item rating differences over the whole data set. I am not so sure yet how to expose that cleanly and consistently. The API methods needed are all there, but nothing more is done to someone craft an explanation of some kind.
