1. For creating sums of the varous numeric columns in your report, take a look at Variables.  You can configure them quite liberly (can sum for all records, those in a group, by page ....).  Very powerful and useful tool.

2. Not sure as I've never used a sub DataSet yet - been out of making reports for about a year, but I'm sure if you search google for that exact question, it'll lead you to some discussion here.

3. Tables are always nice for keeping things 'in their place'.  It's really about flexibility.  If it's going to help provide user controlled dynamic sort/filter capabilities when used with JasperServer, that would be great!
