- They have a slight performance improvement, but unless you run them relatively high i frankly doubt you're going to notice it (it being why you need not rush replacing them)
- What's always a worry with components that are pretty much brand-exclusive is longevity; what if for whatever reason silverstone discontinues the entire 180mm line? What will you do? Run 140s? What, two of them? There are $60 cases out there that have better airflow potential.. all of a sudden, your chassis isn't really where it was anymore. So given that the cost is small, i'd buy and hoard, because as always in life, you never know
Regardless, you're ---strongly--- recommended NOT to run them from any 'normal' fan header, they draw too much power. Control them from whatever you like, but take care in where/how you're powering them; not a coincidence Silverstone ships them as they do, you can literally fry normal fan headers with them. If your level of knowledge is such that this sounds complicated to you, read and learn (air cooling section here), or stick to using them as they expect you to.
Now as to hard drives; newer hard drives are very quiet and have firmware commands you can run that further improves on that (idle spin to name one among many other noise-related functions). Though most have them activated by default anyway, so nothing a user needs to do (a note here that these come with a slight performance degradation). Also, most hard drives, new or old, are just fine running as is -read: without active cooling- so you shouldn't have to worry about temps either unless you run tasks that, by your description.. you don't. So all good on that front too.
What you only want to ensure is that they're protected from vibrations (dampening, special pads, etc).
