Bob, the Snowman from,
Boston, Massachusetts USA
Good morning Bob besides the snow how are things? 
I don't know your level into photography or how much you depend on it for your livehood. Your opinions are simply different than mine and the experience I have had. Over the years I have noticed clients expect a pro photographer to have, well, pro equipment. We used to call it the, uncle Bob with the Rebel, delima. Why am I paying you for something uncle Bob can do for free?
You are going to see the real full time pros using a 1 series or a brand-N D series. They "look" the part. The inconspicuious photographer thing is a myth. People want to know that we are there and with the best pro camera and equipment.
You do whatever it takes to get you the job. If they should say stay out of the way, you do. But that, to me anyway, was very rare.
I have been specifically asked what I intended to use. Many times! Don't ever think that first meeting in the studio doesn't make a big impression.
As to the 135mm, it is my least used lens. It does a nice job filling it's spot in the camera bag. I much prefer the 85mm f1.4.
I am questioning our OP's real desire to become a full time pro. Because he certainly does not need the 85mm and the 135mm in the same bag before he aquires more of the things he does need. Get one or the other, not both, but I recommend the 85mm.
A web site explaining what he offers would be a better idea than to spend money on both of those lenses. But to each his own, there is more than one way to make it. Right?

I'm in a grumpy mood today. (Here in the Boston area, the snowstorm-related collapse of our public transportation system is driving us all nuts.) So here goes:
"The grip makes the camera look more professional"?!! Are you serious? The OP is at most a semi-pro wannabee. His very demanding full-time job leaves him struggling to find time to learn photography and evaluate his equipment needs. How could he possibly care whether his camera makes him "look more professional"? He has enough to worry about just finding potential clients and getting them to take a look at his work. And I'd argue that in most shooting situations the photographer's interest is best served by making himself less, not more, conspicuous. Size wasn't always so highly vererated; in the film days smaller was considered better.
As for grips, they've always struck me as among the least useful tools in a photographer's bag. Unless you really, truly need the extra battery power, a grip adds dead weight for at most a marginal increase in convenience. The extra set of controls for vertical shooting seems silly to me, since I find it just as easy to shoot with my hand above the camera as at the side. I'm as old and arthritic as the next guy, and I don't find it to be a contortion at all. If I'm missing something, I sure don't know what it is. Finally, I'd point out that the cost of a $500 grip is about half the difference between a 6D and a 5D3. Or almost the cost of a top-of-the-line speedlite.
Thanks for letting me get that off of my chest!
