I have do a lot of touring and randonneuring, Your bike is fine as long as it fits and is comfortable.

I would take that $300 and make sure the Bianchi maintenance is up to date.

At most touring and randonneuring speeds, friction is what slows you down. At 10-11 mph, about half your output goes to overcoming wind and half to friction like tires, chain, bearings
.
I would use a fast tire like a 28, 30, or 32 mm Continental GP5000. That would yield you way more speed than those new wheels. I would pay attention to chain maintenance. If your Tiagra bearings are shot (doubtful, they are pretty good for entry level hubs), get the bearings replaced or do it yourself if you have the tools and ability.
