My bike has a triple crank (with Shimano Tiagra shifters and derailleurs). I want to buy a new double crankset. If I do this and install it, will I also need a new front deraillleur, shifter, and/or bottom bracket? Thanks!

You really should have the shorter BB for the double crank,shifters are good,FD will probably work ok.

Rode a Shimano Tiagra triple b4. U must change the BB and the FD(the inner limit for ur current FD will be too deep - the chain will drop).
