The pair stepped off the bench with Blues 1-0 down at half-time at home to Derby last weekend and completely changed the course of the game.
On-loan Thomas netted a brace, his first goals since joining from Bournemouth in January, either side of a first goal of the season for winger Redmond as Lee Clark's side triumphed 3-1.
Skipper Steven Caldwell shrugged off his recent illness to return to the bench and the Scot will now be pushing for a starting place himself at the Riverside.
Pablo Ibanez (groin) should return next week while fellow defender Mitch Hancox remains sidelined with a hamstring complaint alongside long-term absentees Marlon King, Stephen Carr, David Murphy and Will Packwood.
