I've tried using Ice Form shout level 2 (Slen) but I didn't notice any difference compared to level 1 (Iiz). Same goes for throw voice – it however has a lower cooldown, but I couldn't notice anything else. Can someone please explain? Why would I want to be spending Dragon Souls on shouts level 2 and 3?

Higher level shouts usually add more damage, longer effect durations, or more effects at the cost of higher cooldown. (more info here)
For ice form specifically, it increases the amount of time spent frozen and increases the recharge time.
Each shout is different. Some are absolutely awesome at level 3 and lack luster at level 1. Look at Soul Tear for example.
