New innovations for not-new tech.
So your frame relies on a tried-and-true 73mm threaded bottom bracket. Awesome. Here's what we'd recommend. First, pick up Chris King's ingenious new ThreadFit 24 Bottom Bracket. Now, if you are running mountain bike cranks with a 24mm spindle, such as certain Shimano, FSA, Race Face, Rotor, or Surly, you're going to want Chris King Bottom Bracket Conversion Kit #12. The Kit slips onto the crank's spindle and then into the Chris King ThreadFit 24 Bottom Bracket on your bike. If you have any more questions about which CK conversion kit to use, please let us know and we'll help you out.

This is a component of a component so it is easy to forget their utility. I bought a Chris King Thredfit BB for SRAM, then swapped to a Shimano crank. The only thing I needed was the Shimano conversion kit and I was good to go. Very simple once you figure out what you need.
