Should I quit my mariner's career due to myasthenia gravis and how long should I be taking prednisone and mestinone?

Not necessarily. You should discuss all options with neurologist. Also, look at recommendations by myasthenia gravis foundation: http://goo.Gl/3xxmd you could possibly benefit from thymectomy. Another link: http://goo.Gl/9wl9ek.

My husband is taking mestinon, (pyridostigmine) methotrexate, and prednisone for myasthenia gravis. Are all 3 needed?

See below. Myesthenia gravis is an autoimmune disease. That means that the body produces antibodies that attack normal tissue. In the case of mg, the antibodies attack the receptor that chemically links the nerves to the muscles. The Mestinon (pyridostigmine) improves nerve transmission so the muscles work better. The Methotrexate and Prednisone suppress the production of antibodies that attack the receptors. Read more...
Quite possibly. About 1/3 can see spontaneous remission, 1/3 stabilize on chronic medications, and 1/3 have progressive difficulties. In appropriate candidates, minimally invasive thoracic surgery to remove thymus (thymectomy) can possibly cure or stabilize disease or decrease amount and/or types of meds.
