Have read through the instructions on line, but can't seem to find an answer. Can I "join" an AirPort Express to my existing N network (Time Capsule) and then use the ethernet port as an "adapter" for a device (ethernet ready tv in this case)?

No, it absolutely can be used as an adapter. I've used one previously as such - it wirelessly receives the signal and sends it out over the ethernet port. I forget the exact settings, and I've moved on to AirPort Extremes, but IIRC all you need to do is set it up to join the wireless network, don't disable the ethernet port, and then it should work fine.
Ethernet is a two-way street... the internet wouldn't be much good if you couldn't send instructions to it (you wouldn't be able to navigate, for starters...).
