Hi Scott.
Your message almost sounds frantic! But do not worry as there is a simple solution, and I use it with my 2100:
You require the X-10 IR543 to start (About US$20-25). This plugs into the wall and will receive the IR from your 2100 and convert it to X-10 line signals that it will send on the electrical wiring throughout your home (the principal behind X-10).
Next you will need X-10 modules such as plug-in lamp or appliance modules, or wire-in wall switches. for the fan (ceiling fan) you will require an "inductive" wall switch to control its' motor.
A great way to start with X-10 is to purchase the ActiveHome kit (US$50). Visit
www.x10.com. They often have sales and give aways so visit often. Note however that their quality is ok, but not high. Also, the IBM Home Director. This is the same kit with the IBM name stamped on it.
For high quality items and items not available at x10.com, visit such places as
www.homeautomationnet.com , smarthome.com, smarthomeUSA.com, etc.
The remote that comes with the active home kit will allow you to learn the ir signals for X-10 to the sony 2100.
to learn more check out the forum on this website entitled "X-10 Chat".
Have fun!
