text hghlight and auto submition of fields

hi

I made an application using web browser control for auto submition of a site details into web directories. The navifation part works just fine but I need some features work as well.
First of them is to find and highlight in the directory web page the proper cathegory where I like to submit my site. As example let just say i want to submit to bussiness cathegory ... if in the directory exists this cathegory the program will search and highlight bussiness otherwise message("it doesnt exists")
Second feature I need working and this one I dont have a clue how to solve it is to auto fill title,email,description,keywords fields by pressing just one button.
I have in a file all those information abut my site and when I press the button the application will get the datas from my file to the directory fields.
I dont expect anyone to do all the code for me ... but any hints and suggestions are welcomed and apreciated.

thx
