will mountain crankset fit my touring bike

I have a 2010 Novara Randonee touring bike with a Shimano Octalink bottom bracket and a Shimano FC-R453 50/39/30 triple crank. Last year in order to get some lower gears, I swapped the 30 inner ring for a 22 inner ring (or maybe it was a 23) which I got from Universal Cycles. that worked well, but I find that I am only using the four biggest cassette cogs when I am in the 39 chain ring. I never use the 50 at all and can't even imagine why it's on a touring bike. I would like to swap our the 50 and 39 from smaller rings but can't seem to find any that would fit the 130mm middle and outer bolt pattern. so my question is, can I just change the whole crankset to a mountain crankset. The Shimano deore 42/32/22 would give me the gears that I want. Would it fit my Ocatalink BB or would I have to change BBs as well? I only have basic tools and no experience changing BBs. Any advice or suggestions would be greatly appreciated. Thanks
