If you'd like to use JavaScript to grab the letter from the URL query string, run a regular expression on window.location.search:

var letterParam = window.location.search.match(/letter=([a-z])/i), letter;

if (letterParam)
{
    letter = letterParam[1];
}

To match paragraphs starting with that letter, use the charAt() method in JavaScript strings:

if (letter)
{
    $('p').each(function()
    {
        if ($(this).text().charAt(0).toUpperCase() == 'B')
        {
            // Apply the CSS class or change the style...
        }
    });
}
