To start you need three things:

-Soil
-Lights
-Pot

*And of course your seeds (obviously)

Lighting - CFL's are great for beginners and cheap (look into that)

Research those 3 things and you should be at a decent start.

Oh and humidifier and all that other stuff is always GREAT! but optional! unless you really need it because of your enviroment.
You can also get a mini heater/radiator for around $15 CAD or maybe try LOES (US).
