I strongly recommend that you choose your gearing according to your climbing needs, spinning out on descents is much less painful than grinding up steep climbs in a tall gear. Don’t be embarrassed that you need to use such small gearing. Chris Froome used a 34/32 in the Tour de France, too, and last I heard he is quite quick.
I would recommend that you try replace your 11-32 cassette with a 11-40 cassette mountain bike and perhaps also get 46/30 chainrings in the front. Compared to the 11-42 cassette, the gears in the middle are more closely spaced — and I assume these are the gears you will spend the majority of your time in. You should be able to fit this if you add an adapter such as the one already mentioned made by Wolftooth. If you do both modifications, chain ring and cassette, then your cadence (at equal speed) should rise from 50 rpm by 42 % = 1 - (40/30)/(32/34) to 71 rpm. This way you should be in the green again cadence-wise.
