Answer 1

change javascript Address:
<script src="#Url.Content("~/Scripts/jquery-1.5.1.js")" type="text/javascript"></script>
<script src="#Url.Content("~/Scripts/jquery.validate.js")" type="text/javascript"></script>
<script src="#Url.Content("~/Scripts/jquery.validate.unobtrusive.js")" type="text/javascript"></script>
and Html Helper
Html.TextBoxFor(m=>m.UserName)
