how to add note on report parameter dialog box? and how to move headrs to next page?

Hi All,

how to add note (description)on report parameter filter dialog box? and in report design report returns a table structure. if the report design is not fitting in one page, in next page it has to repeat headers in next page or the total table has to go next page.

I already tried with repeat column header on each page and keep together in one page if possible properties. but it is not meeting my requirement.
