If you want the same top end ratios, then 48/32 + 10–29 will give you the same range and more ratios. If it weren’t for the exorbitant price, I’d say Campy’s setup is worth looking into. But you really have to want that new Super Record groupset.
Compared to the SRAM setup the Campag cassette is more tightly spaced at the climby end. That is because a Campy front shift will give you a chainring 16 teeth more or less, and SRAM will only result in a 13-tooth difference. Whether this is an issue depends on your preferences. I like larger jumps between climbing gears. But YMMV.
Practically speaking, you’ll be fine either way. You’ll get used to it.
Gearing is very personal. A 39-tooth chainring seems too large if you really want to climb. (Your gearing suggests that you are encountering proper climbs.)
Staying in the little ring during the base phase seems quite old school 
Maybe you can try different strategies to keep yourself in check. For most endurance rides I give myself HR max targets (e. g. <= 135 bpm or <= 140 bpm) to reign myself in.
