Narrative:

I was flying my second captain trip; and I was practicing my first hgs CAT III approach. So inexperience is definitely a risk factor. We were on approach to land flying a hgs CAT III approach. The weather was calm and clear. Somewhere around the FAF; I became distracted and forgot to call final flaps 30 and the landing checklist. I allowed myself to become completely engrossed by the procedures and callouts. Distraction was the second risk factor. Somewhere below the 500 ft callout; I heard 'too low flaps'. I looked at the flap indicator and saw that the flaps were still at 15. I immediately called 'flaps 30; before landing checklist!' the first officer complied; and by the time we had completed the checklist; the radio altimeter was making the '100; 50; 30; 10'' calls. Things happened so fast that I did not think to go around. Being rushed was the third risk factor. I landed; and realized on landing rollout that 'too low; flaps' is not a caution; but a warning. I was in violation of go around/missed approach requirements.
