If you just want to throw money at it instead of labor, sure get the quickstrut type assemblies that include the spring and mount, but it's really not a big deal to just get the loaner tool from an auto parts store and replace only the strut.
With the vehicle being 2007, many vehicles this age don't need a new mount yet, but you should inspect it and see, similarly you only need new springs if the current ones are sagging. Granted, being able to tell if the mount bearing is shot is sometimes difficult to determine until it's off the vehicle and can be checked for smoothness.
You might want to see if local auto parts stores carry the mount so once it's disassembled if you find it needs replaced, you aren't waiting on mail order (or Amazon if you have prime and can wait a day for delivery in the middle of the repair), can just get it right away if the cost difference isn't much, and you might want to check in a Caravan owners forum to see how much life they're getting out of the mounts, if it's likely to need one.
*Most* vehicles can go through at least a couple pairs of struts before the mounts are shot but a loaded minivan maybe not. Then again, I would consider a loaded minivan to need its first pair of replacement struts before now, already due for 2nd set unless it has few miles on it for its age.
