Not all Cranksets are created Equally.
you should start by listing the cranksets you are considering buying.
your Acera crankset has a 50mm chainline specified... going from 9 to 10 gears in the back won't alter that.
just remove the inner and outer chainrings and check the chainline to the middle chainring to see that it work fine....an increase from 36 to 38 teeth shouldn't cause interference at the chainstay... the diameter increases 3/4", so the teeth will be 3/8" farther to the rear once the 38 Tooth chainring is mounted to your Acera crank.
