But where the 60D has those bonuses it also lacks a fair bit. Those being low light and other details that you can only really get from a FF sensor.
There isn't a detail difference between the two sensors in good light when using their full 18/21 MP resolution for 24" prints. What difference will be observed when their resolution is processed down for video and displayed at a maximum of 2 MP (1080)?
Low light I'll give you. The 5D2 is amazing in low light. But the 60D is pretty good itself.
On the other hand the 5D is a fantastic camera but not really a camera for a beginner. The learning curve is steep and you may be better off sticking with the 60D is you are not 100% dedicated to what you are wanting to do.
In what way does the 5D2 have a steeper learning curve?
As for lenses, The 60D with the Tokina and a 50mm f1.8 (around 80mm on FF) will cover most shots you will need for basic video, maybe even chuck in a cheap 55-250 lens in there too for those shots you need the reach.
Sigma 30 f/1.4 or 50 f/1.4 would be much better choices. The 50 f/1.8 is optically good, but has poor bokeh and is a pain to manually focus, which is even more critical for video.
I'm not sure shallow DoF is a good argument for the 5D2 for video either. Wide open primes on FF are difficult to use in any close situation for still photography. Manually focusing for video? Forget it. You will be stopping down any way.
