There is generally absolutely no need to replace springs. But as noted, 'quick struts' are often more econonomical and should include other parts like upper strut mounts/bearings and the bumpstops and dust covers located inside the spring.
That said, I would 100% not recommend them at all, as most if not all of what you're going to see available as an assembly is the same budget Monroe garbage. Getting all new parts doesn't mean much to me if I feel the damper itself is not worthy of a $5 bill.
Looking at the listings for your specific vehicle, the quick struts are not even as cost-effective as I'm used to seeing. You can buy KYB GR-2's for about 70 a piece, the other parts are about 60. Add in your old springs, and you have, IMO, a much better product for $15 less a side. Just have to invest a little more effort.
If you're not comfortable with 'widowmakers', I'm sure you can find somewhere that will swap your springs out using a real wall-mounted strut compressor for not much money. The scarily-nicknamed widowmakers aren't that bad if you use some common sense, though.
