Answer 1

The function is ok. This is the only way to do it from JavaScript.
If you use a wrapper from jquery, then this will not add speed.
Don't worry, this shouldn't hang the browser, because the browser should have a limit on the number of cookies for one domain, that is, there should be few cookies. In my chrome now this limit is 180 pieces. That is, no one in their right mind will store large amounts of data in cookies, and a hundred pieces are quickly moved in the script.
