Browser Automation?

Browser Automation?

I want to create a little program with following features.
Use proxy in format proxy:port:username:password
Choose a proxy sequentialially from list
Open http://xxxxx.com
Fill Details choosing data from data.txt ( CSV )
Export Cookie,username,password,email address --> cookie.txt
Delete Cookies
Log into associated email account and confirm account by visiting link
sent to that email address.
Then cycle through Step1 again.
I read several similar question on stackoverflow.
I planned to use Selenium for this program, but reading comment here How
to save and restore all cookies with Selenium RC?
the get_cookie method doesn't provide the path, domain, and expiry date
for each cookie, so it isn't possible to fully restore those parameters
with create_cookie. any other ideas
And i won't be able to manipulate cookies using method as describe here

I want to know easiest way to tackle this problem. I plan to run single
threaded application.
