As for the family scenes, they're not logical to put in the movie for one very simple reason: she's gone to Naboo to hide. Her parents' house would be the logical place for a bounty hunter to look...if he were looking for her. I personally don't think they help the love story at all, because they don't deal with the issues that are facing the couple if they wanted to ultimately get together, which are their places in society...
The family scenes slow the movie down too much IMO, and not give any progress. Plus the scenes themselves aren't all that in the first place.
