18.9 is a respectable weight. That's really not bad at all.
Dropping a half pound off that by changing wheels will make a very big difference in how the bike rides, handles, accelerates and holds speed.
It won't feel like a 15 lb Cervelo S5 but you will be able to tell the difference.
I agree with someone who previously mentioned stiffness, which is a good reason to change cranks. Bottom brackets are a good place to gain stiffness as well. Weight might actually be secondary to crank and bottom bracket stiffness in terms of reasons to change cranksets.
