Javascript Adobe Form -- 2

I need to modify an adobe form. The form already has some page spawning and partial javascript implementation. The tasks remaining are to write code to control the formatting of a rich text field. I am looking to lock the font, font size, line spacing, and above/below line spacing. I would like the text whether typed in the field or pasted into the filed to be formatted to Helvetica, 8pt font, with 0 pt spacing above, 0 pt spacing below, and exactly 15.5 pt spacing between lines. Additionally, I need to add a feature to have auto page numbering, cells that remain constant across spawned pages, and the ability to delete pages within the series without causing errors in the unique spawned pages based on a template.
