Chain rubbing on new derailleur and crankset
You can:


lower the front dérailleur, so that the protruding part on the inner side of front dérailleur does not touch the chain.
if the above does not fix, try to re-align the rotation of front derailleur: make it just enough so that it won't rub on the lowest gear
then check if it rubs the chain on the highest gear, i.e. 3 -9 gear. If it does, try to adjust the cable so that it can bring the front dérailleur a bit further away on higest gear. 


If all fails, it's now a trial and error from all the steps I have said.
