You can easily get away with running up to 210 with the stock intake, no problem. The stock exhaust will still work with the 275 tune, but it'll cause your "filter minder" to trigger with the stock intake. If you drove it easily (yeah, who can do that?) with the 275 tune, you could probably get buy till you can get an intake. The tail pipe is a 3.5" mandrel bent and has a strait through muffler. It is probably the best stock exhaust I have eve seen on a truck. Changing it will make your EGT's drop a bit, and probably get your turbos to spool a little quicker, but isn't strictly necessary.
S&B makes a nice quality, and reasonably cheap intake. Any 4" exhaust will do. I prefer something stainless for longevity. 5" is strictly for appearance, it make *no* difference in performance. It does tend to make it sound a little different, but it won't get rid of the "hair dryer" sound completely.
What I did when I Spartan'd my truck was to get a DD with the 75, 150, and 210 DPF delete tunes. You get three ordinary tunes to start with, and they will all work with the stock intake and tail pipe. Then once you get an intake, you could pay the extra for the 275. 275 is well worth it in my opinion. The 310 will be out on the 7th of september. I am thinking that the 310 may need to have a 4" tail pipe.
BTW, I would definitely get a 4" delete pipe, so you will be ready when you do the 4" exhaust. I'm sure there is an adapter that will let you run the 4" delete pipe with the stock exhaust.
