I just did this on my 3600 a few days ago. The instructions with the master cylinder stated to DO NOT BENCH BLEED because you can actually push the rod in too far, said to do it on the truck so that the pedal will limit how far it goes in. So that's what i did, but not with the line hooked up, use a short piece of tubing or whatever you'd normally use when "bench bleeding". After I got the MC bled and filled, I did the RF first. I'm not sure if the 3800 lines run the same, but the trick is to do the wheel that is closest to the MC (meaning how far the fluid travels), and work your way out. Only open one bleeder at a time. I use one of those plastic cups with a rubber hose so brake fluid doesn't go all over and I bleed the brakes different that most people... I open the line first then have someone pump the pedal, then have them hold it when i don't see any more air in that plastic tube, then tighten the bleeder screw (I do this a couple times). Pretty easy that way, when you can actually see if there's air coming out or not. You'll have to fill the MC often. Adjust your brakes then bleed again.
