Changing any light bulbs is simple. The rears are easier than the front if that what you want to hear. Easier by means of you won't have to wash your hands after changing bulbs. The front as you know are cover by the fender liner so it's dirty.
Anyways, I would recommend against the LED bulbs because standard filaments will do the job just fine. LED might short-blind other drivers...depending on how bright they are. Check with your local law enforcement rules on light bulb use.
If you are going to use japan spec taillights then only LED standard are brake lights.
