Even though you don't need to take the front of the engine for this, check that your thermostat still operates normally. It's cheap to replace but if it fails, it can overheat your engine.
If you replace it, check that the new one opens in boiling water before fitting it. I've learnt my lesson...
Also not directly related to a cambelt change, but maybe check the butterfly bushes in the inlet manifold. It's operated by the vacuum thingy at the front of the manifold, and if the bushes are worn it doesn't operate nicely. Worst case it could drop a small piece in the manifold, down in the engine. Not cool...
