I feel your pain. However, the things your gun needs will very well cost far more then the gun would be worth even after they were done.
If some local ham-fist blued the action and the barrels, he may very well have hot blued them and that is attacking the solder that is holding the barrels together. If that is the case, the barrels need to be stripped, polished, and the ribs relayed, then properly rust blued. Stripping the action, making any necessary repairs, polishing off the blue, picking up the engraving and then properly color case hardening the receiver and top-lever has now got you $1500 into this project. Then the trigger guard and forearm iron need to be nitre blued.
If the stock is too badly sanded down there is really no way of ever making that lost wood back. There are some real experts out there in wood repair that may be able to fix the crack to where it is virtually undetectable. A new stock and forearm of even Sterlingworth quality wood is going to be quite pricey. I just checked the high end at Turnbull Restorations (
http://www.turnbullrestoration.com/store.asp?pid=20182 ) a new stock for a box-lock gun is $2200 and a basic forearm is $750 then add the checkering at quote basis!!
