Answer 1

The email address is presented as a claim from the identity provider.

If you're using MVC (for example) an easy way to read the email address is to add some properties to your controller like this:

public ClaimsPrincipal ClaimsPrincipal
{
    get
    {
        return this.User as ClaimsPrincipal;
    }
}

public ClaimsIdentity ClaimsIdentity
{
    get
    {
        return this.ClaimsPrincipal.Identity as ClaimsIdentity;
    }
}

public string UserEmailAddress
{
    get
    {
        foreach (var claim in this.ClaimsIdentity.Claims)
        {
            if (claim.ClaimType == @"http://schemas.xmlsoap.org/ws/2005/05/identity/claims/emailaddress")
            {
                return claim.Value;
            }
        }
        return null;
    }
}

However, Live ID will not give you the email address, or the user's name.
