Doubling Down?

When I was specifying the build for my Rivendell Sam Hillborne just over a year ago, I had no experience with these types of bikes, and went with recommended specs for the major components. For the most part, this has worked out well - with the possible exception of the drivetrain. This Spring I would like to replace the Shimano Deore rear derailleur with the Shimano XT "Shadow," and I am also wondering, whether I would be better off with a double, instead of my current triple crankset. I've mentioned before that I find shifting on this bicycle to be somewhat high maintenance for my taste, with the front derailleur being especially difficult to get into that perfect position where it doesn't rub. I am given to understand that this is fairly typical for a "triple," and that if I want low maintenance I need to switch to a double crankset. With just two chainrings in the front, there is more room and less rubbing.

Switching my triple crankset to a double is something I am willing to undergo, as long as I can keep my current range of gears. This bicycle is used for hills, and I need to keep it that way. And while that is doable in theory, I am not sure what my options are as far as modern cranksets go. The chainrings on my current triple (Sugino XD2) are 46x36x2426 - so I would need to find a double crankset with just the 46x26 rings. Is that even possible? I know that it can be done with vintage-style TA cranksets, but I think I have a cognitive deficiency when it comes to understanding how exactly to buy those: It seems like every single part needs to be purchased from a different seller and they are all super-expensive and frequently out of stock. What other options are there? Someone has suggested simply removing the middle chainring from the current crankset, but I am pretty sure that's not how it's done. If you have a double with a wide touring range, I would love to know what your set-up is.
