Personally, I suggest that the quality of the 7D episode 15-85 is much better, or the quality of the upper red circle 24- 105 is better, and the C format 15-85 is better for shooting wide-angle scenes. Since you are going to be a professional on professional equipment, take two more shots to make up the difference.

The lamp 565 is definitely enough, with high shape index and convenient ttl function; But still need to do professional equipment 580 ii.

Give you a suggestion: skip the flash, don't flash directly, and have an assistant leave the flash if possible. Raw format must be used when shooting to improve the output rate.
