If I were you, I would start by making one dataset that has all the appropriate parameters and conditions on it, and then put it into Table 1 (Summary) and Table 2 (Details).

Your one dataset will have all the details, so you'll let SSRS do the summarizing in Table 1 via SUM and COUNT functions in the table, at least at first (it's slower, but simpler so you're just working with the one dataset). You can break them up into seperate datasets later if you so choose, depending on performancy.

In Table 2 just list all the values from the dataset you wish to display.

In the Properties for Table 1 you can add a page break after it, which will always cause Table 2 to start on a new page.

Play around with it, it sounds like you're most of the way there, but you just need to get familiar with SSRS. Good luck!
