You asked about what else you might need. Super boost chainline should be 55-56.5. If you have a true Super Boost frame, you will need to measure the bottom bracket and see if it is 73, 83, or wider, and either reconfigure your cranks with a longer axle, or if your old cranks have a fixed axle, purchase a set of cranks that fit your bottom bracket.
I ended up liking Race Face Cinch cranks because you can purchase different length axles and bottom brackets, plus they publish a good technical data sheet that show compatibility of frame bottom brackets, chainlines and axle lengths.
