To answer your questions:
1) There are several options for this scenario. In terms of diagnostic tests, bone scan with CT scan, a radiolabeled monoclonal antibody imaging test known as a Prostascint scan are options. Investigational studies include an endorectal MRI as well as PET scanning.
Treatment options can include prostate bed radiation for surgery patients, salvage surgery, cryotherapy or brachytherapy for radiation patients, traditional or non-traditional hormonal therapy, and observation.
In general, radiation for PSA-recurrence after radical prostatectomy provides durable benefit for men and should be discussed.
2) I am not aware of studies involving Calcium glucarate in your situation.
3) Other treatment options (listed above) should all be discussed with your personal urologist.
Followup with your personal physician is essential.
