First, good luck Mike.
This is about as fun and rewarding a thing as you can do. There's nothing like strapping your fist knife on your side and heading into the woods.
To answer your question, you can't solder without effecting the heat treat and if you solder it on first...you can't heat treat it. So you can't get there from here! ;~)
Just kidding of course. Some guys do try to solder, but it does effect the temper of the steel. So no, I would just use brass pins. Peened and epoxied on.
I have to say, I love brass, but peening brass bolsters on a full tang knife is pretty ambitious for a first knife. You can do it for sure, but you'll need to go slow, take your time and ask a bunch of questions. Or if you can find a local maker to bug would be great.
Now, I have a question for you. What kind of steel is that blade? Did your buddy say?
