Williams K4 upgrades?

Hope this is the right place to post this, rather than in the TMCC forum. Came by a good deal on a "new" Williams 5000 K4, which hopefully will be here by summer if the ponies FedEx is using to transport it don't die along the way (already taken a week and just crossed the Mississippi, going coast to coast). 

Obviously, this unit will need some upgrades (especially after seeing the 50's era computer sized reversing "board" in the tender in another post on here). Fresh off of rebuilding an MTH camelback that was missing its electronics, I figure the ERR TMCC and Railsounds Commander boards are a given. Don't suppose anyone's got any package discounts like Boxcar Bill used to offer?

After those, I guess an electro-coupler would be a good addition. Anyone know offhand one that would work well and mount to the Williams tender (and, of course, that's readily available)?

I hear the Seuthe smoke units in these aren't the best. Pretty happy with the output of the MTH one in the camelback, are those available from MTH (part #?), or would I need to hunt one down on ebay? Of course, providing it'll fit... 

If I understand correctly, the "smoke" (feature) connection on the ERR boards simply lets you turn it on and off via a controller such as a Cab 1, correct? I'll probably replace the Williams 4 wire connections with a tether (if the loco board end can be mounted conveniently) just to clean up the looks a bit, and if I don't need wires for the smoke unit, I can stick with a simple 4 wire tether.
