#1 -- The Boston Globe of Jan. 10, 1907 reported the following:
"Treas McBreen (of the Red Sox) said that he had not heard officially that the Boston deal for Thomas Railing of the Dallas, Tex., club had gone through, but the Pres Taylor and Manager Stahl had made an offer for the
player while in Chicago, and the news that the Dallas management had accepted terms was probably correct. Railing is a young fellow, but is a six-footer, and made a splendid record as a southpaw in the Texas League."
So it sounds like Tom Railing is correct identification for #1.

#2 -- The Boston Globe of March 5, 1907 reported on various Red Sox players working out during a spring training session. Railing was mentioned as having pitched, but not looking very promising. More relevant to #2 is the following sentence -- "Tennehill, Oberlin, Killian, Pruiet (sic) and Glaze worked out with the batters this afternoon." With the exception of Killian, all are known to have been pitchers with the 1907 Red Sox during the regular season.
The Boston Globe of Dec. 5, 1906 reported on prospects for spring training the following year. Included on the "official list of new players that the Boston Americans will try out next spring" is: Killian, pitcher, Burlington, Ia. That would seem to be #2.
John Killian didn't have the kind of pitching record which would suggest his being a major league prospect, but I suppose that's always an outside possibility for being the fellow from Burlington, Iowa. He certainly had played for the Burlington minor league team for three years. The link to his B-R.com record is below:
