How many bowlers have over 1000 international wickets?
And has anyone had a longer gap between a first-class match and a Test than Washington Sundar's three years?

Washington Sundar's Test debut, in India's superb win over Australia in Brisbane last month, came well over three years after his previous first-class match, for Tamil Nadu against Baroda in the Ranji Trophy in Vadodara in November 2017. Judging by his efforts at the Gabba, you would expect him to be playing a lot more soon.
You're right that both Muttiah Muralitharan and Shane Warne broke the 1000-wicket barrier when you lump together all three international formats. Murali ended up with 1347 wickets - 800 in Tests and 534 in ODIs (both records), and 13 in T20s - while Warne managed 1001 (708 in Tests and 293 in ODIs).
Ten players have had this bittersweet experience in Tests - although, as most of them were specialist bowlers, the lack of runs probably didn't bother them too much. Muttiah Muralitharan actually did it twice - against Australia in Galle in 2003-04 (he took 11 for 212) and against New Zealand in Wellington in 2006-07 (10 for 118).
I don't think this has happened in international cricket, although it's possible you could unearth a dismissal involving three players called Mohammad. The most famous instance that I am aware of occurred during a County Championship match between Middlesex and Somerset at Lord's in June 1933, when the Middlesex batsman Harry Lee was caught by his brother Frank off the bowling of another brother, Jack. The scorecard entry read "H. W. Lee c F. S. Lee b J. W. Lee 82".
I think the trailblazer here, as with so much in women's cricket, was the former England captain Rachael Heyhoe-Flint, who produced an autobiography called Heyhoe! in 1978. More recently the Association of Cricket Statisticians in England published an interesting account of the life of Heyhoe-Flint's old England team-mate Enid Bakewell, which included excruciating details of how she had all her teeth removed before she was 21.
"Regarding the match between West Indies and England in Kingston in 1973-74, John Jameson took one wicket. I can't find reference to his bowling style but wouldn't it have been spin?"
