Oh man this reminds me of "basic training"
There's several lighting techniques, there's Rembrandt, Paramount, Clamshell etc. but if your on a budget, I'd buy the Impact flash kit for USD $100 and two flashes to get you started. Since you're a Canon user you need a way of triggering the flashes, go for the Elichrom Skyport Universal.
Once you have the lights, start experimenting bounce, swivel, diffuse, and even "Le Louche" the light. Practice makes perfect!
Keep me posted!
