Simple Improvements in a Form - Kohana 2.3 Framework

I have a website running over Kohana 2.3 Framework and I need to do enhancements in some fields of a form. The data is coming good but some of them are being displaying in an inappropriate way for the user to edit them, like a set of records being shown in a single input text separated by semicolon instead of being in different input texts. What I need is just to improve the usability to the user inserting Jquery calendars (I already have the code), radiobuttons, and multiple tags selection (I already have the code). It's about 12 fields to be improved. Please check the detailed brief and the form's screenshot attached to this project before you bid.
