yeah, the Nemesis was a pushover! I think you should be able to build him as whatever class you want, but with no dailies. And like 12 health. It was still a tough fight, but if the party saves its dailies for the boss, it can still be over pretty quickly.
Also, check out how I've used wikicode template blocks to create the "NPC cards" on other wiki pages.
All in all, it was a lot of fun! I want to see more modules like that -- ones that are sort of open ended, and have a lot of potential RP involved with them but nothing scripted too strictly. Things which would be a building block in your character's narrative.
It was also very short - only one encounter. As such, maybe the nemesis should get daily skills after all. hmmm I wonder
