Without knowing your fitness or how you get up tough climbs with your current gearing this would be hard to call for us CC folk. Jimbo will bring some interesting science to the table when he enters the fold.
I would say a 34x28 as suggested would probably be ample allowing you to hopefully spin at a reasonable cadence sitting down. Some people I cycle with though stand up on the gears I sit and spin at, it depends on how you find the longer steep drags.
