And I highly value your opinion, since you are almost exactly what I aspire to be. Yeah, yeah - "don't feed his ego" and all that, but it's the truth. I look at your work and am just in awe of it. I say "almost exactly" since there are some back end differences between our lives, what with you being single and me having a wife and two kids.
But on the job, my goal is to get to the quality and sheer awe of the images and moments that you have captured. I know I've got my work cut out for me to get from where I am, to where I want to be. But I also know that I need the proper equipment - and there's so much of it that I don't know what the best progression is.
Hey Jeremy, thanks for the compliments. I hope i don't have that much of an EGO! I feel that i'm pretty modest, except when in the lighting forum, because they are a bunch of knuckleheads. Myself included 
I can assure you though, the grass is always greener.
You don't see me posting the bad side of things, insane brides and their parents threatening us with legal action, bad reviews etc... it's not all fun and games. Not suggesting you think it is, but just in case someone else may think that.
But in any case, i'd personally bulk up on speedlites and glass at first. With those cheap triggers you can use them off camera instead of studio strobes. You don't need to be overpowering the sun or anything.
My personal lens choice for weddings is the 35L, 70-200 2.8, 85L and occassionally the 14L all on a FF. Everyone is different. The 24-70 is a great all around lens, but i've owned 4 copies and all 4 have never lived up to the quality when viewing at 100%. That's not to say it's not a good lens, it's a great utility lens, no doubt. In fact we still have 2 for the fact that it's a very handy length.
Knowing that you have the 24-70, i'd personally next go to a 70-200 2.8. Then you'll have long covered, 24-70 covers the wide, maybe an ultra wide for some interior shots? The Sigma 12-24 on the 5D is spectacular and won't break the bank.
Picking up a secondary 580 speelite would be high on my list as well.
Hopefully that helps.
