Gearing question

My road bike has the following gearing,

(50-34) & (25-12)

I am about to do a couple of hilly rides (The Chiltern 100) and I have been given a compatible cassette which is (28-11).

This to my rather basic knowledge seems like a no-brainer, I'll get a bigger range at both ends, won't I?

Is it as simple as that?
Will I notice a significant difference for climbing?
Is it a straightforward job?

Thanks for any thoughts.

    It will be easier to climb but slower. You will also be able to pedal down hills for longer. Drawback: the ratios between the gears are greater, but it aint that serious.
