There is a misconception that you need a flash so tight your horse can't breathe.. untrue.
Also, I am completely unsure of the bit you are using.. different terminology!
I once had a TBx (not raced, mind) and I took her from the last hoop on a three link Dutch gag to a double jointed snaffle- gave her something to play with.
As for the bridle, so long as colour matches you should be fine! You don't need a specialist bridle for hacking/jumping/dressage etc.
