Wheels won't improve your ride comfort if that is what you are seeking better wheels for. Get better tires for that.
If you do a lot of riding at a high speed that has tight turns and other technical things to challenge you then you might need a better set of wheels that lets you feel the road better. Otherwise, weight will likely be the only benefit, and that might not be much depending on what exact model rims and hubs are on your bike right now. Some alloy rims aren't very much heavier than some carbon rims.
So again if your demands for cornering performance and being able to sense the road through your bike isn't one of your needs and talents yet, then just ride some more and save the money for a better bike.
