No doubt the throttle body will be too, and the inlet manifold.
And.....the ducting to and from the intercooler, the intercooler itself....
Is there a method of cleaning all of this, and any tips on reducing/preventing the build up?

There's no way to stop it.
Get yourself some carb cleaner and give it a good scrub. Its a very messy job though, so make sure you cover your floor and wear gloves if you can. I know lots of people don't like wearing them, but if you don't, you'll be scrubbing your hands and the pipework too.
