Don't bother with resistors, and just buy Canbus Compatible Leds. This will keep bulb burnt out messages/indicators from coming on if you have them. If not, then don't worry about it at all.
For your hyperflash, do you have a mechanical flasher relay? Rockauto says you do. Tridon sells an EP27 electronic LED flasher relay that should cure your hyperflash.
