Yes, I can also confirm that you get both types of spells, regardless of when you dual from ranger to cleric (even one level of ranger is enough). If you start as a ranger, go to the priest spell screen. You'll notice that the screen is not greyed out like it is for fighters, thieves, etc. That is because they already have access to all of the druid spells; they are just not high enough level to get slots yet (thus the reason no spells show up). However, the moment you get the cleric spell slots, you now have slots for the level, so once your ranger class reactivates, you get the access to all the druid spells again. Good to dual early if you want to play a cleric with both druid and cleric spells (i.e. not worried about fighting ability). Personally, I play through the entire series a lot of times, so I usually multiclass.
