To answer your questions, if you want to change the compact two pieces crankset with triple then you need new front brifter and new front derailleur (for 3 sp) and some adjustment with your outer bb.
But then alternatively to get lower gear, you can use 9 sp mtb sprocket and a little training to get used to it.
