Those grates don't look like the anthracite specific ones we all know and love. You may want a bent pick to poke from below to keep them open.

Don't worry about poking at'em they work fine, poking induces undue stress to anthracite it is a moody fuel that likes privacy and as little human contact as possible
Good that you were able to find a source for replacements there is one on line here but I have never thought to save the link.
You will find that the meeting edge of the components that make up the grate system all have a taper to them so they don't just fall in but actually work together to support itself which is why I questioned how they could possibly work if broke, this also prevents the Flip It
idea from working .
One time some ash built up under one of the supporting ears of mine and slipped off causing the whole left side to drop down near the ash pan and lock up the whole thing I figured the worse case scenario Broken Grate but was happy when I disassembled and found it slipped now when I service it which is only once a year I remove the grates and supports to clean behind the ears to speak.
While its down take this opportunity to remove the side covers this will give access to the manifold remove the end caps near the rear of the manifold and vacuum it out, I know the feeling of not wanting to go that far and thinking that reaching in with a hose from both fire box ports and chimney connector flange is good enough but one time after half stepping the job I pushed myself to do it right and was shocked at how much got missed . A little penetrating oil on the studs an hour before you start always makes it easier and they can be resealed with flat rope gasket and a couple of spots of gasket cement from a hardware store . When reassembling the wing nuts on the studs need only be tightened a quarter turn past finger tight .
Remember the passage way of the manifold is relatively small and all of it must be utilized for the stove to give the least amount of problems .
Also vacuum the little duct from the thermostat flap to the fire box during operation this is the fires only source of air and again it is relatively small .
The pipe off your stove looks fine, you will need your own expertise or the help of a chimney Guy to determine the condition and performance of the main chimney you are tieing into .
Rule of thumb is .04-.05 on a manometer at times mine runs a bit less so I'm cautions and having done this for a long time I got a few tricks up my sleeve for when the temperature, humidity, and barometric pressure throws my main chimney out of wack but I don't discuss them here, they are tricks and in the wrong hands dangerous .
They are grate
