Hi Joe,
The IGI has the marriage date in Ramsey as 27 Nov. 1864, husband aged 27, wife aged 20, and the LDS source film number as 0106182.
The fathers' names and occupations (and other details) should be in the parish register marriage entry. I only have Maughold ones, sorry, but you can order the film very cheaply to view at any Family History Centre (under Church of Jesus Christ of Latter Day Saints, in the phone book) or search for the closest one at: http://www.familysearch.org/Eng/Library/FHC/frameset_fhc.asp.
John Thomas Edwards could have been born after the start of civil regt in 1837. Free BMD has a birth Sep quarter 1838: Edwards John Thomas [district] Gt.Yarmouth [vol] 13 [page] 315, but I'd get the marriage details first so that you know his father's name.
