Now what about the tarp? What is the best for using a stove in? I know silnylon is not the best. Any suggestions.

If I go to a stove my thought is to make a large griz beak type end with a stove panel in it. For a 3" pipe I would think a 14 -16 inch square of nomex with an aluminum or stainless metal panel around 8" with an oval hole. Put the panel maybe 1/3 down from the top of the add on. Considering this would usually go into a canoe camping or winter hike with a pulk setup urethane coated nylon seems reasonable. Pair it with a large rectangle tarp and you get a lot of options including setting it up in a separate space. One could probably do the package for under 5 lbs..
Here is a source of fireproof fabric: http://fireproofblankets.com/
Generally, a welding blanket will work, or siliconized fiberglass. You can find many tarp maufacturers online who make custom welding shields. Ten bucks for a yard square piece is not bad, but you may be able to find it for less with a good google search.
I make cross + shaped cut on mine where the length of the slits is equal to the diameter of my stove pipe. I then insert the pipe throught the slit and mark the outline of the inserted pipe on the stove jack. I then pull out the pipe and use high temperature stove silicone to make a bead all around the mark, and I put an extra dab at the end of each slit to keep it from tearing.
I'd go 6-8 inches larger than the outside diameter of my stove pipe to avoid melting my tarp. You can sew the fireproof fabric right over your tarp and then cut out the tarp material after it has been sewn in place.
If you go through the tarp, you have a place where water can leak in when using the tarp without the stove pipe in place, however you can make a silnylon cover and attach it with velcro.
If you go out through a grizbeak, you don't have to worry about water leaking, but heat rises, so with a horizontal run of pipe, you have to worry about melting the tarp over the pipe and making sure the pipe runs uphill enough to get the smoke to rise. Also, if the grizbeak flaps, there is a risk of disconnecting the pipe from the stove, which can be a major disaster.
One thing that hasn't been mentioned and is worth thinking about when planning one of these builds is that the stove pipe itself is probably the main radiator of heat in one of these rigs.
For that reason, having the pipe exit the tent/tarp/tipi/whatever at the highest point possible is always desirable and keeping the pipe away from sidewalls is too. Pipe can get very very hot.

Hey Rbinhood, have you ordered fabric from those guys? All the sources I tried really killed you on shipping, actually making it cheaper to buy stuff from tigoat.
ymmv and I'm not affiliated with tigoat at all, that's just the best stuff I could find for the overall price.
Oh and on a side note, I called one of these fire blanket makers and got hung up on when I told them what I wanted the fabric for...

I got a 6'x6' piece for about $25.00, including the shipping, but I can't recall who I ordered it from.
I guess you shouldn't have told them what you were planning to do with it and it really isn't any of their business. Sometimes, less information is better, depending on who you are dealing with.
Most metal mailboxes nowadays are aluminum, which would be lighter, but degrade almost immediately from the heat. Stainless steel mailboxes in the general shape are available, but costs are outrageous. $150+????? Don't even want to think how much a titanium mailbox would be!
