1) if the stock fits use it how it is if its the correct stock for the rifle
2) use a small punch with a flat tip to get the pin out it comes out the top
3) head space is just a tollerence factor to cover the variences in rims by different ammo makers. the way I do it is to set the head space for the ammo I am using by finding a bolt head that will close firmly on the brand of brass I am using in that rifle. rims on S&B are thinner than rims on RG 44 so if you intend to reload its best to set it so its firm on the brass you use.

I would be checking the bolt for proper fit at the locking lugs before going on to head space it
The bolt needs to be in full contact on the bearing surfaces in the receiver if not disaster might be in your future
