Since you're on a budget, try to find a used Canon T2i on eBay. For a lens, I'd suggest a 24mm 2.8 (since your room is pretty small).  If you have an iPhone, you can use a Rode SmartLav for your mic and record audio onto your phone.

For lights, just get some clamp lights from the hardware store and plug them into a Router Speed Control (they work great as dimmers):
