Wow! This thread is STILL going?! It's like the energizer bunny...it just keeps going and going and going.
See you're still experiencing some serious issues with your wood burning endeavors. I read through a bunch of pages just now and it seems it might make sense to ask Metalbestos about whether you need a spark arrester screen in your current setup- and I'd send them the pictures of your creosote buildup to help them understand your particular situation. After all they make the pipe so they ought to be able to offer some insight.
And I see you're going to get yourself a real saw- a Stihl! Yahoo! See my signature....
I note you mentioned the 'sawdust' in one post. If your saw is cutting correctly you won't be seeing dust you'll be seeing 'chips' of wood.
If you get a new saw, with an EZ start system you'll have to adjust to the way they start. Especially restarting after running one for a while. It is quite different than the way older saws start, and one has to be careful to realize that when you pull on the cord the saw will likely start with almost no effort. I found this quite disconcerting at first and hard to adjust to, for me, after being so used to drop starting saws all my life and having to pull the cords like there was no tomorrow. Make sure they demo a saw for you so you can determine if it's right for you.
I also noticed when you showed pics of your stove door open it seems the gasket cord around the stove door is maybe not sealing as tight as it should. (It's hard to tell from the pics for certain). Open the doors and look at the imprint of the seal on the stove face, both left and right, and check the rope seal in it's groove to see if it could fit better which will give you better draft up the flue thus creating a hotter fire, etc. There ought to be a way to adjust the tightness of the doors and gasket.
If it were me I wouldn't allow for any throttled down fires at any time, day or night. You ought to be burning as hot a fire as possible to prevent creosote buildup. I'd remove the spark arrester, after discussing it with Metalbestos first, and see what happens with creosote buildup. I doubt you have a hot enough temp at the top of the flue to cause any fire issues greater than the one you have already with the flue being blocked with creosote. If the creosote at the flue cap were to ignite it's being balled up on top of your chimney in the end of the flue and contained by the spark arrester could result in an unstoppable 2000* fireball ending up on your roof - much worse than a few errant sparks.
I would also supplement your current wet wood with some dry as you could possibly find wood from someone who could sell you a few cords.
And if you can't get to cut up all your current wood supply of logs at least get the bark off them so they stop rotting and drawing insects to the wood, which will end up in your house reeking havoc.
I'd also have a few fire stopping Chimfex 'flare' like safety extinguishers that could be put into the insert to smother a fire if it got out of control. They are shaped just like a road flare but are designed to kill the fire in an emergency. See the video:

One other thought about how you handle your wood. If it were me I'd use the pallet forks and lift the logs up, placing one across the forks, and cut them from each end toward the forks and when I could cut no further then use the Peavey to hold the remaining section off the ground. I would also cut each section of length, say, 16" along the entire log length and then roll the log over on the forks to cut through the rest of the way.
