I know this is not close to you, but Kenmore Camera in Seattle is worth a visit. They'll give you good advice, they'll have a ton of used gear so you can at least put your hands on the bodies that are on your short list. And they'll have good technical advice from their staff. Also, a place like Kenmore usually has rentals. So if you think you're going to spend $1,400 on a package, you can usually rent it for 3 days to play with it. This is a very good idea once you have a body you know and are looking to add lens to your collection--try before you buy.
Once you've made your decision, two places that have great reputations for on-line used gear are
KEH Camera and
Adorama Camera. I know it probably feels uneasy to buy used gear online but their stuff will be checked, come with a warranty, and usually have a return policy. Do NOT buy used gear on Amazon. There are occasionally scams (I've reported 3 of them where Nikon body prices were too good to be true). I did buy one Nikon body from a third party via Amazon and it turned out to be gray market (which means Nikon won't repair it when I needed work done).
Good luck making your decision and I look forward to seeing your photos.
