Your 34/32 with a Compact crank will give you slightly lower gearing than 30/27 on a triple so I can't see a major problem for you. Unless you are completely unfit (Meaning bike fit so you probably are) and your hills are long and steep. However you might have more confidence if a triple is fitted but confidence doesn't get you up hills.
Just take a gentle route for a month or so and gradually get up to the steep hills. And in a few months time you will find that this question was not your major concern for your first foray into modern bikes. Now Butt ache--------- and you will have a problem.
