JP, Great selection. I don't think you could do better than what you have, other than adding to the available variety.
You show #4 on your wanna-list as "OF 100". Since you already have Old Fitz 100, I'm guessing you mean Old Forester. That's a really good bourbon and certainly worth having, but I wouldn't recommend that you shell out for the 1.75 bottle; it's not THAT unique and spectacular.
#5, EW single barrel is quite tasty, and it would be nice to have one in your collection. But unless you want to specialize in a collection of single-barrel offerings year after year, it really isn't any better than what you already have. The same can be said for the Old Forester Birthday Bourbons; any one of them is great, but the real treat is to compare year after year, since they're all quite different from one another.
#2, You can order VOB from Binny's (http://www.binnys.com/all/barton#/?page=1) and probably other online sources as well. You should. Neither myself nor the Goddess are particularly enamored with Very Old Barton (in any proof; they have several), but many bourbon enthusiasts (as well as most Kentucky bourbon drinkers) prefer that brand to all others. It belongs in your collection.
Also, Mogollon Brewing Company, in Flagstaff, is a regional small brewery that also distills whiskey from its beer mash. This isn't bourbon, of course, since the major (perhaps only) grain is malted barley, but it's worth getting a bottle for your collection. And for bringing to any of the gatherings you might attend, since that would be a totally IMPOSSIBLE whiskey for any of the rest of us to have tasted.
