Answer 1

If I'm understanding what you are trying to do correctly the below should work with minimal reflection:

public static MvcHtmlString MakeTable<TModel, TValue>(this HtmlHelper<TModel> html, IEnumerable<TValue> table)
{
    var modelMetaData = ModelMetadataProviders.Current.GetMetadataForType(null, typeof(TValue));

    foreach (TValue row in table)
    {
        //write out table
    }
}

To get properties:

YourModel.GetType().GetProperties();

To get the name of a property:

property.Name;

To get the value of a property:

var result = YourModel.GetType().InvokeMember("NameOfProperty", BindingFlags.GetProperty, null, YourModel, null);
