+1 for VIsionColor. Their VisionTech profile is great for Canon cameras, far better than the CineStyle profile in my opinion. VisionColor also sells a pack of LUTs called "Osiris" that look GREAT slapped on top of footage shot with the VT profile. Also, Magic Bullet Film and Looks might be worth looking into. Film involves a lot more tweaking, but Looks has a lot of really good looking presets. When I was starting to color grade, I would select a Look, place it on a clip, and I would try to emulate the Look on another clip with no effects. It was a pretty good exercise to learn about warm, cool, contrast etc. But I'm not sure how far along you are now after watching that tutorial video. It sounds like you've gotten a lot out of it.
