Nicely done there! Whoop!
I hate to break it to you, but I don't think that crab pot is salvageable.
For the prop, I've had good luck with both Krueger and the Mukilteo Prop Shop (don't ask me whether its the prop shop or the prop shop, I can never remember). We are actually blessed in this area on having a number of good shops, all doing reputable work. Have not dealt with Northlake but have heard good things.
5200 is evil and those who use it for stuff like this should be stoned. Actually being Seattle, if they use it, they probably are stoned.
I'd pull and chop that shaft too, but do some rough measuring as it looks like you may also need to have the bow lowered a bit to get it out. Don't ask why I know to anticipate this.
I like to have this kind of stuff as easily serviceable as possible, best to get it sorted now. Things have a bad way of winding up in this condition when you are north of Nanaimo and its not quite so convenient to work on. I don't know why, but it seems to be the land of dinette table generator rebuilds and other similar adventures.
