Welcome to the site Bones. Glad to have you aboard. I think you'll find that most guys on this site are here to help you.
You have picked a rifle well. The dirty-ought-six is as versatile as any rifle out there. The only thing I might suggest is to use good quality bullets. There are a lot of them out there, so pick wisely. I would use something in the 180 grain area and a good quality bullet, like the Nosler Partition or A-Frame.
As far as binoculars, those may very well be one of the most important items you need to get. As Critter said, buy the BEST you can afford. This is an area not to skip on as you'll have those puppies up to your eyes a lot of the time. $200 is a starting point, but you can spend a lot more. If not, choose a good starting pair and start saving for better ones.
Let me suggest a good pack.... Dwight Schuh puts out a unit that has a fanny pack and a day pack, both attached to an external frame. They can be removed and the pack used to haul meat. I have carried out several elk on this lightweight frame and couldn't be any happier. If you can find one, they sell for around a hundred bucks.
Please find shoes that fit well and you can put a lot of miles on. They can make or break your hunt.
Sounds like you are putting a lot of thought into this new adventure. Stay tuned to this site and I'm sure some very knowledgeable people will help guide you in the right direction.
