Remington 870 crowning question.

Remington 870 crowning question. So, I'm not sure if this should go here, or in the gunsmithing section, but I think it's more shotgun related than gunsmithing related, so I"m going to post it here.

I recently acquired as part of a trade a Remington 870 wingmaster that someone has bubba'd into a tactical gun.
The barrel is cut down to 20" - I think, but I haven't measured it yet - and it looks like it was done with either a dremel of a hacksaw. Not pretty.

So, my goal is to turn it into a usable and more attractive turkey/HD gun, and I have a few questions.

First and really most important, how likely is it that I can get the remainder of the barrel tapped to take screw in chokes? And, what's that likely to cost? Is it something that the average run of the mill smith should be able to do, or is it something that I should send away and have done by a specialist?
Would is be a better idea to just try to get it re crowned, and find something else for hunting?

Second, since I have no bead anyway, and I like ghost rings I was looking at the XS banded front sight. Does anyone have experience with it? It seems sturdier than the soldered versions, and would certainly be easy to install. They're not exactly cheap, but trijicon would probably be useful for hunting in the woods, and it would certainly work well for use as an HD gun.

Lastly, is has an atrocious hard plastic pistol grip stock on it right now. I was planning on finding a classic looking set of wood stocks, but if I'm planning on hauling it around the woods all day would something synthetic - like magpul's new stock - be preferable. In looking at the new guns it seems like most of the turkey guns are synthetic, so I assume there's some sort of reason.

Thanks in advance, and I'll be sure to post some pictures once I have some "afters" to go with the "befores".
