Hi James,
1 - In the Report Attributes for the tabular form, you have an option "Number of Rows (Item)" in which you can specify a page item name (eg, "P1_ROWS"). Obviously, you will also need such an item on your page - typically, this is a Select List with Submit (but could be a normal select list if you intend to reload the page using a button click).
2 - Do you mean a search across all fields on a displayed tabular form or a filter to restrict the rows displayed?
3 - A Process (which is what I think you mean) has a "When Button Pressed" option which allows you to pick the button that triggers your process.
4 - This depends on the checkbox and whether or not you have more than one checkbox. A simpler solution would, perhaps, be to have a select list with the required values (even if that is just "Yes" and "No")
5 - This depends on what the popup page is designed to do. You could look at the following as a starting point:

If 2 and 4 are both to do with filtering the data, then you need to add a WHERE clause to the underlying SQL statement. Something like:
SELECT...
FROM ...
WHERE FIELDX := :P1_PAGE_FIELD
OR FIELDY LIKE '%' || :P1_STRING_SEARCH || '%'
The exact format would depend on the data type of the field being filtered.
You also need to have something on the page that will trigger the page refresh which is required so that the filter can be applied. Normally, this is an unconditional branch (ie, a branch that is not triggered by a button) that branches back to the same page. In the branch definition, you also need to set the "Set these items" and "With these values" to pass back to the page the values in the search fields (eg, P1_STRING_SEARCH needs to be passed back into itself otherwise the field's value is lost when the page reloads and the filter won't be applied). If you are performing a filter using multiple fields, then you would normally apply the filter using a button on the page, so you would select this button as the trigger for the branch - again, this is a "When Button Pressed" setting on the branch definition.
