End joining trim, staining, etc

I'm working on the perimeter trim for my tear's sides and am planning to join the sections together with epoxy/biscuits, then router/jigsaw to shape. After the initial mock-up pieces shown here, I've made my final pieces from clear pine and have the slots cut ready to join. Not being much of a woodworker, I'm wondering if I should stain all my pieces, epoxy them together, sand the face of the joined strip, restain, coat with epoxy to seal or what? I don't want epoxy to fill the wood grain and not allow the stain to reach all areas around the glue joints if I don't stain first. Most of the trim I see on the site almost looks like one piece. I need some advise from those that know.
