Probably not: Paraganglioma are uncommon tumors of the paraganglia system, used to control blood oxygen levels. Cardiac paraganglia are very rare. The lymph node you describe is only slightly enlarged, and so is unlikely to represent metastatic disease. A scintigraphy (sestamibi or fdg) study is better able to detect metastatic disease.

Difficult to say: Without a biopsy. It should be a relatively easy and safe fine needle aspiration. Ask your doctor. http://www.mayoclinic.com/images/image_popup/c7_needlebiopsy.jpg.
