I tried to leave the sidequests for alt levelling where I could. For me they were basically gone after my 2nd class got to 50.
You should definitely unlock and leverage the challenge log. It's sped up my alt class levelling a good deal. Also the guildhests now grant the 1st time bonus xp for each class that does them rather than just one time.
