No one is going to hammer you here. It is a very newbie friendly place. Once you become a regular, you will be open game for a little good natured ribbing.

For the trigger I would reccomend Sharp Shooter Supply, very nice trigger, very easy to install yourself.

For your barrel, page down to the vendor classified section and look under Northlander Shooting Supplies. Jim appears to have an unfired SS fluted 204 barrel in stock. Jim is a great guy to deal with.

Post any questions you have along the way, someone will be here to help.

BTW, if you don't like that ugly black bolt body, I would be happy to trade you a nice shiny silver one for it.
