Choosing bicycle gearing is a bit too complicated to give advice over an internet forum.
Someone who knows what they are doing, an experienced racer and is a qualified fitness instructor needs to see the person who's asking, see the bike, get a brief of the countryside the person is intending to ride, and above all, get a good idea of the person's capabilities.
This, I'm afraid is beyond a ten page thread on CycleChat.
If the OP knows a LBS where the owner is an ex racer and coaches young cyclists, he should go and chat there.
