Fucky wucky, any tips?

My valve stem seals went bad, so after popping the vc off to start the work, I noticed my timing chain could definitely use an replacement (181xxx miles) This is the first time I'd be doing anything really intensive with the motor, in terms of teardown. So, my question is, what all do I need to get this done. I already have basic hex/torx bits, basic metric socket set both standard and deep in 3/8-1/2. Camshaft lock and 1/2" drive torque wrench. Is there anything else I'd need tk get to do this? Any tips and tricks?
