Not really. A prayer to help is primarily a prayer for his councel as one who is human and has reached salvation.
That is desperate, as even if this were primarily what PTDS consisted of then it would still not explain why they did not not pray to angels when seeking protection and deliverance, as Catholics prayers to angels do now. Meanwhile the reality is that is that prayers to the departed abound with beseeching them to intercede, as in "I implore of you to obtain for me" (prayer to St. Anthony; http://www.catholic.org/clife/prayers/prayer.php?s=41), and to "strengthen me in my faith; establish me in virtue; guard me in the conflict," (prayer to patron saint) and to act in other ways which are seen in Catholic prayers to angels, which also can appeal to their compassion. (Glorious Prince of the heavenly hosts and victor over rebellious spirits, be mindful of me who am so weak and sinful and yet so prone to pride and ambition. - Prayer to Saint Michael for Powerful Aid). And prayer to Mary includes ones that make her an angel, and more so. (Sovereign Mistress of the Angels,..Who Is Like Unto God! O good and tender Mother!).
Moreover, Catholic prayers to angels asking for help, protection and deliverance (including your St. Martyr George, help me kill this dragon) would also be fitting in the OT, but not even a prayer to Michael the Archangel can produce even one! The utter lack of which there is no excuse for if PTDS is to be supported by Scripture as doctrine.
May the lizard of Luther be slayed for the ages. Amen.
An unanswered prayer.
Even though angels were present while saints simply were not there was no Mediator between men and God the Father revealed to the Jews; the concept is uniquely Christian. Further, I answered in the sentence you quoted: a saint is someone very much like me, who has overcome sin under the leadership of the Holy Ghost; an angel is someone I cannot model myself after.
