42-32 is 34.5 gear inches, enough for everything but really long climbs. Heck, i've got 36-25 as the low on one bike, which is 37.9 gear inches-- maintaining any climbing cadence in that gear gets tiresome after awhile. My 1X bike has an 11-42 cassette, but I spend most climbs in the 42-32. For commuting, you should be just fine.
