but there’s a metal bar or pin stuck in it and no i dea how to get it out.

The pin usually has a larger diameter on one side and by the looks of the pin you tried to knock it out the wrong way. I would try knocking it back, then cutting the damaged section off of the pin and use a drift punch to knock it out the other side. In the end you may wind up drilling it out. A 3" nail will work as a replacement pin.

That little "deep" spot could account for the resistance you're feeling, basically it's just the change in direction (roller going down then suddenly going up). If the track feels smooth then I reckon your best bet is to just start using it.

As mentioned the pin is tapered and can be knocked out pretty easy using  the right size drift one way or the other. It is very important not to use a hammer to get the pulley off . The best and safest way is to use a 3 jaw gear puller .

Without feeling or listening to the machine i cant really say if it needs any attention . Is it just a little stiff or does it actually bind to a standstill ?

The groove in the pulley is CNC machined to a tight tolerance is i would not mess with it . The bearing that runs inside it is replaceable and is softer metal therefore sacrificial . I would just persist with running it for about 1/2 a mile of stitching and see what happens from there
