Took it back in for them to do the work.. Having them save the old parts and give them back to me. Apparently, they have to buy and install a new bottom bracket, to go along with the new crank. So, they are replacing the crank, cassette, fixing the brake line, and replacing the bottom bracket. Final estimate is $169... $55 is labor. They said they won't have to replace the chain since it's so new (I've had it for a few weeks only).
