Answer 1

Try

var results = _MiscContext.Database.SqlQuery<int>(
              "exec sp_GetStaff {0}",
              customerNumber).ToList();

Answer 2

Since you're using named parameters, you have to specify the matching name for the parameter you're passing.

var results = _MiscContext.Database.SqlQuery<int>(
    "exec sp_GetStaff @custid",
    new SqlParameter("custid", customerNumber)).ToList<int>();
