Help, scan document then make it template to add text to

How do I do this, scanning a document as a TIFF or using a text recognition program to create a template, then making a place were I can edit text, or add text to the document scanned?

steps I think?
1) scan document as TIFF
2) convert to PDF
3) use a PDF form filler? like http://code.google.com/p/formulatepro/downloads/detail?name=FormulatePro-0.0.6.dmg
